First of all, I question whether attractive women really have more children. A woman's educational and socioeconomic background plays a huge role in determining how many kids she'll have - less-educated women from poor backgrounds tend to have the most kids. They are also more likely to be overweight. Well-educated women with good incomes tend to be healthier and take better care of themselves - and have fewer children.

Furthermore, attractive women have unattractive children all the time. Girls do not always look like their mothers - sometimes they look more like their father or a relative.
