Give scientific reasons for the following statements:
Each new generation through sexual mode of reproduction will end up in equal number of chromosomes and the DNA content instead of double to its parents.

Explanation

In sexual mode of reproduction, each new generation is the combination of the DNA copies from two parents. Each new generation gets twice the amount of DNA compared to that with the previous generation.
But reduction division i.e., meiosis occurs during gamete formation. As a result germ cells have half the number of chromosomes and half the amount of DNA set as compared to the non- reproductive body cells.
When haploid germ cells from two parents fuse during sexual reproduction, it results in diploid zygote. Chromosomes and the DNA content in new generation is thus reestablished.
