A human body cell would have 46 chromosomes. Since a human egg cell is a reproductive cell (sex cell), it would contain only half the number of chromosomes as a body cell. Thus, a human egg cell would have 23 chromosomes. A sex cell has half the number of chromosomes for a good reason. When two sex cells reproduce, they combine to form double the number of chromosomes. So when two cells with 23 chromosomes each reproduce, the offspring would have 46 chromosomes.
WHAT IS A TRUE EGG? âEggsâ are produced in the ovaries, BUT these are not true eggs yet, and will never complete meiosis (a special type of cell division) and become true eggs unless OR until they are first fertilized by a sperm. Within the ovary, a follicle consists of one potential egg cell surrounded by special cells to nourish and protect it. HOW MANY EGGS DOES A WOMAN ACTUALLY HAVE? A human female typically has about 400,000 follicles/potential eggs, all formed before birth. Only several hundred (about 480) of these âeggsâ will actually ever be released during her reproductive years.
