A diploid organism has ten homologous chromosome pairs.Disregarding crossing over,how many genetically different gametes are possible?

Question

Quizplus · Accepted Answer

If a diploid organism has ten homologous chromosome pairs, it has 20 chromosomes in total.

During meiosis, homologous chromosomes separate and end up in different cells. Each chromosome can independently assort as maternal or paternal.

Therefore, the number of genetically different gametes is 2^n, where n is the number of chromosome pairs.

In this case, 2^10 = 1024, so there are 1024 genetically different gametes possible.
