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

Answers (1)

Ans.

Meiosis is also known as the reductional division is responsible for the formation of gametes. Meiosis reduces the number of chromosomes to half in male and female gametes.

For example, an organism with the diploid condition (2n) has 20 chromosomes, then its gametes are haploid (n) with 10 chromosomes.

After fertilization of the male (n) and female gametes (n), the zygote formed will be diploid (2n). Hence, fertilization restores the normal chromosome number of organisms.
