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?

Best ResponseYou've already chosen the best response.4but the chromosomes do not have to be identical e.g in men, there are two sex gametes, paired together X and Y gamete

Best ResponseYou've already chosen the best response.3@DrAmaQueen Do you mean to say that human gametes have 23 chromosomes?

DrAmaQueen

Best ResponseYou've already chosen the best response.4or rather i would say that each chromosome in the pair is a gamete

Best ResponseYou've already chosen the best response.3Body cells have 23 pairs of chromosomes. That's 46 in all.

Best ResponseYou've already chosen the best response.4yeah, 44 autosomes and 2 sex chromosomes

Best ResponseYou've already chosen the best response.3That'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??

Best ResponseYou've already chosen the best response.0Yes I am thinking what it was. A1A2 and B1B2.

Best ResponseYou've already chosen the best response.4yeah 2 pairs means four in all

Best ResponseYou've already chosen the best response.0If we assume A1 and A2 represent the homologous chromosomes.

Best ResponseYou've already chosen the best response.4then meiotic division brings it down to a pair

Best ResponseYou've already chosen the best response.3lol 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.

Best ResponseYou've already chosen the best response.4in a diploid cell, there would be twice the normal number gametes

Best ResponseYou've already chosen the best response.0edancer98 do you get how to do this question?

Best ResponseYou've already chosen the best response.0I did then it got complicated with too many answers so I'm thinking. :/ Gonna scroll up.

Best ResponseYou've already chosen the best response.4the 23 pairs of chromosome in a haploid cell make a single gamete

Best ResponseYou've already chosen the best response.0Ok then, as you have got it I'll leave this here for reference.

Best ResponseYou've already chosen the best response.0Two 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.

Best ResponseYou've already chosen the best response.0But the question did say combinations so yeah.

Best ResponseYou've already chosen the best response.4the question is confusing, am not even sure what they are asking for, could you rephrase it?

Best ResponseYou've already chosen the best response.0I can't that was the whole question. :(

Best ResponseYou've already chosen the best response.4how many different combinations of chromosome

edancer98

Best ResponseYou've already chosen the best response.0Two pairs of homogous chromsomes.

DrAmaQueen

Best ResponseYou've already chosen the best response.4in the gamete, the chromosome would be paired in fours(2 pairs)

Best ResponseYou've already chosen the best response.0lol this only took 30 minutes for me to get it xP

Best ResponseYou've already chosen the best response.4homologous means that the 2 chromosomes in a pair would have the same genetic material

DrAmaQueen
 one year ago
Best ResponseYou've already chosen the best response.4in a haploid cell, there are 22 homologous pairs, cause the last pair which is the sex chromosome pair is not homologous

DrAmaQueen
 one year ago
Best ResponseYou've already chosen the best response.4so in a diploid cell, i would assume there are 44 homologous pairs
