Chromosomes


Humans typically have 22 pairs of chromosomes (one donated from each biological parents) plus a 23rd pair that are the sex chromosomes. Typically, a female human has two “X” chromosomes, and a male human has an “X” and a “Y” chromosome—for a total of 46 chromosomes. A sperm is the smallest human cell. The ovum is the largest human cell. With more research and advanced equipment, however, it has been discovered that some individuals have more than 46 chromosomes. Up to 49 chromosomes have been identified in some studies. The extra chromosomes tend to be multiples of the two sex chromosomes: “X” or “Y”.
