11. How is the normal number of chromosome restored in a progeny?
Answers
Answer:
This happens through sexual reproduction. When the male and female gamete (both of which are haploid) fuse with each other, a zygote is formed which is diploid. This zygote develops to form the offspring. So every cell in the offspring will now have the diploid set, i.e. the normal number of chromosomes.

Explanation:
In sexually reproducing organisms, the gametes undergo meiosis and hence, each gamete contains only half set of chromosomes. When two gametes fuse, the zygote formed contains the full set of chromosomes. Hence, the formation of gametes by meiosis helps to maintain the number of chromosomes in progenies.
