Generally, an individual need 23 pairs regarding chromosomes, totaling 46, 1 / 2 of arises from the fresh mom’s egg and you will half is inspired by new father’s spunk.

While a masculine, there are XY chromosome, whenever you are a lady, there’ll be XX, as you can see, which is why why Triple X Syndrome is additionally called (47, XXX). Despite the problem, it’s relatively popular and you may takes place in throughout the one in step one,000 girls/female.
