WebApr 8, 2024 · 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. WebThe number of sets of chromosomes in a cell is called its ploidy level. Haploid cells contain one set of chromosomes. Cells containing two sets of chromosomes are called diploid. If the reproductive cycle is to continue, the diploid cell must somehow reduce its number of chromosome sets before fertilization can occur again, or there will be a ...
