Explain how, offspring and parents of organisms

Reproduction (C10)

Explain how, offspring and parents of organisms reproducing sexually have the same number of chromosomes.

Answer

In sexually reproducing organisms male and female gametes/ reproductive cells with only half the number of chromosomes (as in the parent cell) are produced. During fertilization, when male and female gametes fuse to give rise to a zygote, original number of chromosomes are restored.
