Question: Recall that alleles of a single gene will segregate from one another during anaphase i. when do alleles for two different genes—located in two different chromosomes—segregate?
In this blog post, we will review the concept of independent assortment of chromosomes and how it relates to the segregation of alleles for different genes. Recall that alleles of a single gene will segregate from one another during anaphase I. When do alleles for two different genes—located in two different chromosomes—segregate? The answer is also during anaphase I, but not necessarily at the same time. This is because the orientation of each pair of homologous chromosomes on the metaphase plate is random and independent of other pairs. Therefore, the combination of maternal and paternal chromosomes that end up in each gamete is also random and independent. This means that the alleles for two different genes can be inherited in any possible combination, as long as they are located on different chromosomes. This is the principle of independent assortment, which was first proposed by Gregor Mendel based on his experiments with pea plants.
