Summarize the results of one of the first investigations of the genetics of skin color
What will be an ideal response?
One of the first investigations of the genetics of skin color, done between 1910 and 1914, studied black–white marriages in Bermuda and in the Caribbean. The results illustrate several properties of traits controlled by more than one gene. The F1 generation had skin colors intermediate to those of their parents. In the F2, a small number of children were as white as one grandparent, a small number were as black as the other grandparent, and most had skin color between those two extremes. Because F2 individuals could be grouped into five phenotypic classes, the investigators hypothesized that two gene pairs control skin color. Each F2 phenotypic class represented a genotype produced by the segregation and assortment of two gene pairs.
