Question

5. When does the segregation of pairs of alleles (homologous chromosomes) take place?

(a) During the first set of meiotic divisions (Meiosis I)
(b) During fertilization
(c) During the second set of meiotic divisions (Meiosis II)
(d) During Mitosis

Answer 1

(a) During the first set of meiotic divisions (Meiosis I). This is when homologous chromosomes, each carrying a pair of alleles, separate and move to different daughter cells. This results in the formation of haploid cells containing only one allele from each homologous pair.

Answer 2

(a) During the first set of meiotic divisions (Meiosis I)

Step-by-step explanation:

The segregation of pairs of alleles, which are located on homologous chromosomes, occurs during the first set of meiotic divisions, also known as Meiosis I.
