Comment on the statement - Meiosis enables the conservation of specific chromosome number of each species even though the process per se, results in reduction of chromosome number.

Solution

Meiosis is called reduction division because the number of chromosomes in daughter cells becomes half of the number of chromosomes In mother cells. In spite of this. meiosis enables the conservation of specific chromosome number of each species. In fact, has there been no meiosis. organisms would not have been able to evolve to sexual mode of reproduction. We know that fertilization involves fusion of male and female gametes. Thus, zygote gets the chromosome pool from two cells and the number of chromosomes in a zygote becomes double that of the gametes. To ensure conservation of specific chromosome number after fertilization. It is necessary that the gametes should have half the number of chromosomes compared to what it is in somatic cells.
