Which Type Of Animal Cells Have 1/2 The Usual Type Of Chromosomes?
All gametes have half the number of chromosomes than other cells like nerve cells and muscle cells. Sperm is the gamete here. The female counterpart of the sperm is the ovum. There is a reason as to why these cells have half the number of chromosomes. Actually what happens during fertilization is that both the sperm and the ovum fuse together to form a zygote. The zygote then further develops into an embryo, a fetus and eventually a baby. Now imagine if both gametes had the diploid number of chromosomes. In that case, the number of chromosomes in the zygote would be double that of the number of chromosomes in parents. Humans have 46 chromosomes. Imagine if both gametes had 46 chromosomes, the baby would have 92 chromosomes. That means, the number of chromosomes would double after every generation. If that was the case, we humans would mutate and look different in every generation! However, since both gametes have half the number of chromosomes, that is 23 chromosomes, the baby would ha
