Question

According to Mendel’s law of segregation, what happens to chromosomes during meiosis?

A. Homologous chromosome pairs line up in the center of the cell.

B. Homozygous chromosome pairs attach to their centromeres.

C. Homologous chromosome pairs pull away from each other.

D. Heterozygous chromosome pairs undergo crossing over.

Answer 1

Answer : The correct answer is -

C. Homologous chromosome pairs pull away from each other.

As per the Law of segregation of Mendel, during the process of formation of gamete (haploid, sex cell such as egg and sperm), the variant of gene (allele) are separated from each other so that each gamete receives only one allele.

As the chromosome number is reduced to half in gametes (haploid), therefore during the process of meiosis, homologous chromosome pairs are pulled apart from each other, which ultimately give reproductive cells (gametes).

Thus, option C) is the right answer.
