Question

A husband has 46 chromosomes. His wife has 46 Chromosomes. Then why do not their offspring
has 46 pairs of chromosome which is obtained by the fusion of male and female gametes? Support
your answer with neat illustration? ​

Answer 1

Explanation:

Male individual has 46 chromosomes but because the gametes are always haploid i.e. they have half the no. of chromosomes; sperms will be haploid 23 chromosomes. The female individual also contains only 23 chromosomes in egg. It is the fusion of this sperm and egg which leads to an offspring with 46 chromosomes.
