Tomond,
Thank you for the site on heredity. It is very informative but it does not explain how a person's heredity seems to depend largely on the order in which they were born and the sex of the first child (and first pregnancy) in a family. What I have observed both in my own family and in many others is that if the first child (and first pregancy) is a girl, she will look more like her father than her mother. The next child to be born, regardless of sex, will resemble the mother. If there is a third child, that child (again regardless of sex) will look like the father (and so on). If the first child in a family is a boy, he will look more like the mother and the second child (regardless of sex) will look more like the father.
I just don't understand how that happends.
