Question

The number of chromosomes is reduced to half in first reduction division of meiosis, then what is the need for second mitotic division?

• A. For the segregation of replicated chromosomes
• B. For equal distribution of haploid chromosomes
• C. For the formation of four gametes
• D. For equal distribution of genes on chromosomes

Answer 1

The correct option is A For the segregation of replicated chromosomes

The meiosis has two stages of division, meiosis I & meiosis II which are reductional & equational divisions respectively. The first meiotic division leads to the reduction of the chromosome number to half i.e haploid condition, the second meiotic division results in the formation of four different daughter cells which are haploid in number, it provides a physical basis for the law of segregation and independent assortment.

So, the correct answer is"For the segregation of replicated chromosomes".
