Question

Why do germ cells have half the number of chromosomes?

Sarina Biswas · Accepted Answer

Germ cells have half the number of chromosome because after fusion
of male and female germ cell the zygote will have diploid number of
chromosome in it which is normal But if there were more than half
number of chromosome in germ cell than after fusion of germ cells
the zygote would have abnormal number of chromosome in it It is so
to maintain the consistent number of chromosomes in each species of
organisms If the number of chromosomes in not reduced to half in
the germ cells, the zygote or the offspring will have double the
number of chromosomes that in parents and so on which will disturb
the body design and function of organisms"
