menstruation & fertilisation.
- / 12:28 AM.
menstruation.
when menstruation occurs, the unwanted egg dissolves, and the lining on the uterus wall is shed.
fertilisation.
however, if sexual intercourse were to take place within 48 hours of the release of the egg, the egg might be fertilised. only ONE sperm will succeed in entering the egg, while a barrier will be formed to block out other sperms. the head will break off from the sperm, and its nucleus will fuse with the egg's nucleus.
both the sperm and egg have 23 chromosones, which contain genes that decide on how you look like, your height, and other features of your body.
