This case explores how skin color is inherited in humans, presented in the story of Catherine and Richard Howarth whose children are surprisingly light skinned compared to their Nigerian mother. Based on what you have learned about polygenic inheritance, explain how Richard and Catherine Howarth were able to produce light-skinned babies. Are the odds indeed 1 in a million?

Does a person who is colorblind have a homozygous or heterozygous pair of genes for this particular trait?
