Answer 2

Experts estimate that there are 60,000 to 100,000 genes (made up of DNA) in a human being's 46 chromosomes. A baby gets 23 chromosomes from his mother and 23 from his father. With all the possible gene combinations, one pair of parents has the potential to produce 64 trillion different children. This probably gives you an idea of how impossible it is to predict just what your baby will look like. T
