Question

How is equal genetic contribution of male and female parents ensured in the progeny??

Answer 1

During sexual reproduction, a female gamete (egg) fuses with a malegamete (sperm) which are haploid to form diploid zygote. The zygote contains 23 chromosomes from mother and 23 chromosomes fromfather. Thus, half the number of chromosomes come from mother and half from father. In this way, an equal genetic contribution of male and female parents is ensured in the progeny.

Answer 2

Equal genetic contribution of male and female parents is ensured in the progeny as the haploid sperm fertilises with the haploid egg to produce diploid zygote which has equal number of chromosomes from the male and the female.
