genes and reproduction; are there genetic diff each of the eggs that a woman produces.
Are there genetic differences in the eggs that a woman produces. What I mean is that a woman can produce hundreds of eggs in a lifetime. Are each of these eggs genetically dif from each other. The same question applies to sperm. Is each sperm a man produces genetically diff from all the others? I ask this question because I am trying to understand how children with the same parents are not genetically the same. They are similar but they don't look the same nor do the necessarily have the same skills or abilities. Is it because the eggs and sperm themselves are slightly different?
