Question

pairs of chromosomes present in human egg cell(with explanation)​

Answer 1

Answer:

An egg or sperm only has half of the parent's sex chromosome pair. An egg will always have an X chromosome, since the woman's sex chromosome pair only has Xs. Sperm can have either an X chromosome or a Y chromosome. If a sperm with an X chromosome fertilizes the egg, the new cell will have two X chromosomes

Answer 2

Unlike all the other cells in a human body which are diploid, human sex cells are haploid. That means that both sperm cells and ova are haploid; containing only 23 chromosomes. ... When the sex cells are being formed, they take only one of each pair, ending up with 23 unpaired chromosomes each.
