has an unusually high frequency of the gene that causes Huntington
original Dutch colonists just
happened to carry that gene with unusually high frequency
The Afrikaners are an example of a founder effect that occurs when
population and the random decrease in genetic variation is an example
A)
genetic drift.
natural selection
