@bookworm00981 what would you say if there was asexual reproduction.
what was that for?
i think ryaan was trying to take revenge
No man :/ It's not revenge
I studied recently about that! So got lil confuse! I want to make clear to myself about it! If anyone knows about it explain me!
no problem it happens .you know i also did this once
asexual reproduction happens with only one parent so to make the fertilization to happen a lot of genetic material is needed.but in sexual reproution two parents involved so less genetic material are neededd
dont get confused with meiosis because it is a cell division.
http://www.biologyreference.com/Se-T/Sexual-Reproduction-Evolution-of.html read this you'll get your answer
In contrast, sexually reproducing individuals spend a considerable amount of time and energy locating mates, exchanging genetic material, and often caring for young. Sexual reproduction begins with production of sex cells via meiosis , a process that halves the genetic material of each parent in preparation for combination with another sex cell. Consequently, a sexually reproducing parent transfers only 50 percent of its genetic material to each offspring. This loss in genetic contribution to each offspring is known as the cost of meiosis. In addition to this cost, males produce enough sperm to fertilize the eggs of many females, yet many males in some species never even fertilize one egg, resulting in many wasted sperm. In light of all of these disadvantages, why did sexual reproduction evolve? For some plants, spore-forming protozoans, and invertebrates, sexual reproduction may yield seeds or eggs that are resistant to harsh environments and are capable of being dispersed. However, scientists agree that the most important advantage of sexual reproduction is the variation produced by the continual recombination of sex cells to create unique individuals. In 1930, Ronald A. Fisher noted in The Genetical Theory of Natural Selection that this variation allowed evolution to occur at a faster rate. This idea led to two theories explaining how increased genetic variation might benefit individuals.

Sexual reproduction begins with production of sex cells via meiosis , a process that halves the genetic material of each parent ? Does it mean ''some genetic material is wasted''? ''confused''
third sentence of that little paragraph i just put up!
When genetic material is halved ...It means is genetic material is wasted??
Some genetic material*
yes yes it does.... This loss in genetic contribution to each offspring is known as the cost of meiosis.
@Ryaan trust me you are right it is Meiosis
I just asked my Biology teacher she said the answer was meiosis
in this case jasmine is right but if we compare more genetic material is used because of the less chance of fertilization
i mean asexual repro
well lets do some more research I'll brb...@Ryaan how much time do you have to answer this....is this question flvs??
I just want someone to explain me this with logical answer! :I
Jas ! It's my own question.. I want to understand it!
okay okay....look in your textbook
let ryan know the basic first then go to complecated topics.don't you know that genetic material is mostly wasted in asexual reproduction.debating is useless
@thomaster isnt it asexual reproduction
@Blaze No, it's either sexual reproduction or meiosis
ou said it is asexual reproduction this is the definition of Asexual reproduction: A form of reproduction in which new individuals are formed from one parent without the involvement of gametes
I TOLD YA!!! it has to be Meiosis because A form of reproduction in which an offspring is formed from the combination of two gametes, one from each parent
^Way to act mature about it
everyone said i was wrong
Asexual reproduction CARRY half of genetic material ? Does it mean ''genetic material wastes''???
In meiosis, 50% of the genetic material is wasted (because only half of the material from male and female are used) In sexual reproduction, like 99.999% of the genetic material is wasted because only 1 sperm cell out of millions fertilizes the egg. Not quite sure what answer they're expection for this question
DEFINITION OF MEIOSIS Meiosis: process of nuclear division in cells during which the number of chromosomes per cell is reduced by half through the separation of homologous chromosomes
While in meiosis ''genetic material becomes halved''? right? U_U So confused!!
halved means wasted the answer is meiosis
well...igtg good luck i still know the answer is Meiosis
hm I confused some things... in meiosis, not 50% of parents material is used. That's supposed to be sexual reproduction. Sorry for the confusion :P
see more genetic material is produce in asexual reprouction and some are used so much of it are wasted.
If you look at the process of meiosis. You'll see that all of the material is used to create 4 haploid cells. So if I had to answer this question, i'd say in sexual reproduction some genetic material is wasted.
i dont agree anyway bye
@thomaster SEXUAL REPRODUCTION? u__u
@blaze in asexual reproduction, no gametes are involved. So there's no material to lose. Asexual reproduction is just cloning.
It is true that in meiosis the genetic material is halved, but each of those hapoloid daughter cells can be used in sexual reproduction. In sexual reproduction, half of the female gamete's genetic material and half of the male gamete's genetic material is combined.
what do you mean by "wasted"?
in meiosis, genetic material isn't "wasted". Sure it's divided in half, but those halves are used for the daughter cells.
Then what is meant by 'wasted''?? That's so confusing
Well it was a question! not totally my own creation! So I asked it!
So in what process exactly I can say ''A genetic material' wastes'' Hmm Yahoo answers! I don't believe them!
Sexual? Asexual? Meiosis?
I would say DNA replication, because the end of telomeres are not replicated, but they're not "wasted". or maybe during transcription, in the splicing process, some of the RNA is cleaved (introns) and recycled.
According to the answers given above by those people Now all seems correct in a way! :c
Or is it specifically in a reproductive process?
Nvm! I should stop this question then! I just wanted to make it clear to myself! while I have become more confuse! Thanks everyone!
i don't see how genetic material would be wasted in any reproductive process.
I'm going to ask my book author!
Yeah, let me know what he/she means. You might be translating "wasted" incorrectly.
Not me! that book's author! U_U
haha sorry, the author might be translating "wasted" incorrectly (and ambiguously).
@aaronq you could see spermatozoa as the carriers of genetic material right? Only 1 out of millions gets to fertilize the ovum. The rest will die, thus their genetic material is 'wasted'. At least that's how I would think when I had to answer this question.
hmm i see what you mean, @thomaster. Although, meiosis is not a exclusive process for sperm production, it also occurs for female gametes which aren't "wasted". The person who wrote the original question could have had a better word choice.
I didn't mean meiosis was the answer :P I meant sexual reproduction.
OH, sorry. I just figured because everyone kept talking about meiosis. But, yeah that makes more sense as an answer in the larger scheme of things.
Yeah you are right it's "Meiosis"
No, I don't think so @kingkhan94
Ok Thomaster then I would like to now what do you think?
@kingkhan94 Read my previous posts, I did explain my reasoning there.
Genetic material is not used: doesn't mean genetic material wastes..<.<
I have got the answer ! :-D It is deletion :Loss of genetic material=genetic material wasted And it is caused by errors in chromosomal crossover during MEIOSIS..
hm "loss" is not synonymous with "wasted". Also, mutations are very seldom (not frequent enough to have a significant loss).
Okay then ? Only 1 out of millions gets to fertilize the ovum. The rest will die, thus their genetic material is 'wasted'.??? How genetic material wastes here ??
@aaronq http://www.merriam-webster.com/thesaurus/waste[noun] See: Loss is a related word with waste..
there is hormones will help the fertilized ovum to change and complete it growing .. exactly the follicles inside the ovum until it be ready to enter fallopian tube to arrive to uterus
Only 1 out of millions gets to fertilize the ovum. The rest will die, thus their genetic material is 'wasted'. Wasted because the sperm (containing DNA) will die and, hence, be wasted. I personally don't agree with the question and if this question was in one of my tests i would contest the meaning of "wasted" in it. Because "wasted" is everyday speech, and necessarily accurate when you're talking about biological processes.
and other sperms will die .. cuz no environment like ovum .. and it will do outside of body as a remains or body wastes
I would interpret wasted as "Not profitably used or maintained" Which is exactly what happens when the remaining sperm cells die.
what are you asking exactly ryaan?
That book's author contact no :P @mary.rojas
hopeless case .. i really wish to know whats ur questions exactly talkin about ?? i read all answers and really that was enough ... right !!!
This question is still ''Unanswered'' according to me! I'll find the exact answer of this ''wasted genetic material'' someday :p! But I'll have to reasearch and to study about it more!!......
That author sure would have something strange in his mind, that he made that question! So this question sure have a answer.....
You're thinking too much into it. The confusion comes from the author's poor choice of words.
look genetic materials must be with sperms .. genetic materials has that discriptions in sperms .. like eyes color and tall ...... so when the sperms enter body u know there is one sperm will enter ovum and this sperm must have this genetic materials .. some of this genetic material will do effects on fetus shape and fetus properites and sizes of fetus organs ... and there is another genetic matrerial will not do any effect on fetus .. this geneitc materials called wasted genetic materials with that what u want
forgive me @Ryaan because I gave you Wrong information.Actually I mixed it up with internal and external fertilization.
@ryaan Isn't there an answer sheet or something similar included with the book?
Ill give you an eg. Hope this helps. During meiosis in the egg cell, first the 2 chromosomes in the homologous pair get separated into 2 daughter cells. Then the 2 chromatids of each chromosome separate. So this now becomes haploid. Now you have 4 cells. Out of these 4 , 3 disintegrate and only 1 egg cell remains. So in a way you lose the genetic material present in the disintegrated cells.
Hope this clears ur confusion
so was I right??
Well there's a big confusion about the question author's choise of words... In a way you're correct, but more answers are correct. It is true that you lose some genetic material during meiosis, same for sexual reproduction. In sequal reproduction, you'll lose pretty much every bit of genetic information because only 1 out of the millions of spermatozoa fertilizes the egg, and the rest dies. So maybe the word "some" in the question makes meiosis the correct answer but I guess we'll never know unless @ryaan has the answer sheet.
shrutipande9 makes a good point. But since the same logic can't be applied to male gametogenesis (meiosis), the argument is not uniform for both cases, and so it fails.
Umm I would also like to add that during fertilization only one male gamete fertilizes the egg while the others disintegrate. So in a way it works for both. But as thomaster said the problem is the choice of words. In any process like meiosis we cannot term it as genetic material wasted unless and until the process is chromosomal aberration wherein u actually lose genetic material.
removal of introns?
Removal of introns is the process in which genetic material wastes? @abb0t
Pre-transcription is where excision of introns occurs.
removal of introns occur when dna is transcribed into rna. even though they are spliced the original info is still intact in the dna
so i dont think it can be termed as genetic material wasted.
@Ryaan this ques has confused me a lot....nyc 1!!!!!
itx notttt meiosis...!!!
it can be chromosomal aberrations. in this deletions occur and then nucleases act on the broken fragment. so inturn genetic material is lost. i am damn sure about this now.
@Ryaan dis is ur ans.
Answer is Meiosis. I don't know why! The term ''Genetic material is wasted'' is used here as MEIOSIS! Thanks Gonna close this now!
It's not really the process in which genetic material WASTES.
That Baka Author used ''GENETIC MATERIAL WASTED'' for MEIOSIS.
