Best Answer

There are 23 chromosomes in a human sperm or egg (ovum).

Of these, 22 are autosomes, and there is one sex chromosome: either an X or a Y. So 23 is the human haploid number.

These haploid gametes each have 1/2 the set of human chromosomes, 23 chromosomes. This may when a zygote is formed the standard diploid number of chromosomes, 46 chromosomes, is there.

Has how many chromosomes withn the egg cells?

All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.

Why is it important to have half as many chromosomes as normal body cells?

The gametes must have half as many chromosomes as normal body cells because they unite to form a zygote, which is the first body cell of the new organism. For example, human body cells have 46 chromosomes and human gametes (sperm and egg cells) have 23 chromosomes. When the sperm fertilizes the egg, the zygote will have 46 chromosomes, and is the first body cell of the new human.
