Solution

In sexually reproducing parents,the germ cells have half the number of chromosomes and DNA as compared to the non reproductive cells of the body. when these germ cells , i.e sperms and ova combine with each other at the time of sexual reproduction,the original chromosome number is attained in the zygote. This zygote further develops into a complete individual having the same chromosome number as present in the parents.
