Question
“The chromosomes number of the sexually reproducing parents and their offspring is the same.” Justify this statement.
Solution
In sexually reproducing parents, the germ cells have half the number of chromosomes and DNA as compared to the other 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.
