Question

Is there any relationship in the number of chromosomes of meiocytes and gametes?

Answer 1

Hint:A meiocyte is a kind of cell that differentiates into a gamete via the procedure of meiosis. Through meiosis, the diploid meiocyte divides into 4 haploid gametes. In sexually reproducing organisms the meiocytes give rise to haploid gametes, which on fertilization produces zygote.

Complete answer:
Gametes are of two types ie male gamete (sperm) and female gamete (ovum).
1. Spermatogenesis:- It is the process of production of male gametes i.e. sperms. Sperms are haploid male gametes which are produced from spermatogonia which are diploid cells. Spermatogonia is diploid, it is a type of meiocyte as it gives rise to gametes in meiosis.
2. Oogenesis:- It is a type of gametogenesis in females. In this a haploid ovum is produced in the end from the oogonia cells which are diploid. Here the oogonia acts as meiocyte as it undergoes meiosis and gives rise to haploid ovum. All this process takes place in the female ovaries.
Gametogenesis explains that it is the process that results in the formation of haploid cells (n) from a diploid (2n) with the aid of meiosis and cell differentiation.
It is clear from the above discussion that yes there is a relationship between the number of chromosomes of meiocytes and gametes of the same species. As on meiosis meiocyte gives rise to gametes. So the number of chromosomes in gametes is half to the number of chromosomes in meiocyte. For example- If the chromosome number is 2n in meiocyte then the chromosome number in gamete would be n.

Note:
It ought to be remembered that spermatogenesis is the formation of spermatozoa from spermatogonia, spermiogenesis is the development of spermatozoa from immature spermatids and spermiation is the launch of sperm from the testes. Also in the course of oogenesis, there is the formation of three polar bodies and now not two due to the fact that the first polar body divides into two.
