Really need help now please. :( A diploid cell has two pairs of homologous chromosomes. How many different combinations of chromosomes could there be in the gametes?

but the chromosomes do not have to be identical e.g in men, there are two sex gametes, paired together X and Y gamete
anonymous
  • anonymous
@DrAmaQueen Do you mean to say that human gametes have 23 chromosomes?
anonymous
  • anonymous
or rather i would say that each chromosome in the pair is a gamete
anonymous
  • anonymous
they have 23 pairs
anonymous
  • anonymous
Body cells have 23 pairs of chromosomes. That's 46 in all.
anonymous
  • anonymous
yeah, 44 autosomes and 2 sex chromosomes
anonymous
  • anonymous
Thankyou both. :)
anonymous
  • anonymous
works the same for animals, don't know about plants don't do botany lol
anonymous
  • anonymous
anytime
anonymous
  • anonymous
That's right, in humans. 44 autosomes, 2 sex chromosomes. And you know that human gametes have half that number? ~~~~~~~~ I read the question. It says....a diploid cell has two pairs of homologous chromosomes. 2 pairs of homologous chromosomes.... as in FOUR chromosomes in all?? Like a spider mite??
anonymous
  • anonymous
Yes I am thinking what it was. A1A2 and B1B2.
anonymous
  • anonymous
yeah 2 pairs means four in all
anonymous
  • anonymous
If we assume A1 and A2 represent the homologous chromosomes.
anonymous
  • anonymous
then meiotic division brings it down to a pair
anonymous
  • anonymous
I'm surrounded by smart people.
anonymous
  • anonymous
lol So it really isn't talking about humans. A hypothetical question that happens to apply to spider mites. Funny. I'm sorry for misinterpreting it though.
anonymous
  • anonymous
dats ok
anonymous
  • anonymous
:P
anonymous
  • anonymous
now that i look at it ...........
anonymous
  • anonymous
in a diploid cell, there would be twice the normal number gametes
anonymous
  • anonymous
edancer98 do you get how to do this question?
anonymous
  • anonymous
haha christ!!!
anonymous
  • anonymous
sorry correction
anonymous
  • anonymous
I did then it got complicated with too many answers so I'm thinking. :/ Gonna scroll up.

the 23 pairs of chromosome in a haploid cell make a single gamete
anonymous
  • anonymous
Ok think I got it. Thanks everyone. :D
anonymous
  • anonymous
we made a mountain out of a mole hill
anonymous
  • anonymous
haha yup. I'll probably post another question later. xP I'll close this one.
anonymous
  • anonymous
Ok then, as you have got it I'll leave this here for reference.
anonymous
  • anonymous
Two pairs of homologous chromosomes: Let's call them A1 A2 and B1 B2. A1 could pair with B1 or B2 in the gametes - this means there are two combinations. A2 could pair with B1 or B2. That's another two. Therefore, there are four overall combinations. I guess recombination could give rise to more differences.
anonymous
  • anonymous
But the question did say combinations so yeah.
anonymous
  • anonymous
the question is confusing, am not even sure what they are asking for, could you rephrase it?
anonymous
  • anonymous
I can't that was the whole question. :(
anonymous
  • anonymous
Normally I love biology but this is insane.
anonymous
  • anonymous
ok lets take it slow
anonymous
  • anonymous
how many different combinations of chromosome
anonymous
  • anonymous
Two pairs of homogous chromsomes.
anonymous
  • anonymous
in the gamete, the chromosome would be paired in fours(2 pairs)
anonymous
  • anonymous
yes
anonymous
  • anonymous
lol this only took 30 minutes for me to get it xP
anonymous
  • anonymous
haha
anonymous
  • anonymous
homologous means that the 2 chromosomes in a pair would have the same genetic material
anonymous
  • anonymous
uh huh
anonymous
  • anonymous
in a haploid cell, there are 22 homologous pairs, cause the last pair which is the sex chromosome pair is not homologous
anonymous
  • anonymous
so in a diploid cell, i would assume there are 44 homologous pairs
anonymous
  • anonymous
TAHNKYOU! What is your IQ? :O
anonymous
  • anonymous
like 2 :D
anonymous
  • anonymous
lol it's clearly higher than mine since I just typed thankyou wrong
anonymous
  • anonymous
roflmfao it took a great deal of time to be sure of what they were even asking for, if i took that long in exam i would be sent to study agriculture
anonymous
  • anonymous
hahahaha XD I better close this question now

what ever girlll or should i say grill! lol im so stressed right now.....
anonymous
  • anonymous
So stressed we can't even read powerpoints right anymore.
