Final Jeopardy! Albinism is a recessive disorder resulting in very pale features. Create a pedigree! Two normally-pigmented parents have 3 kids. First child (girl) and their second (boy) are normal. Third child (girl) has albinism. That girl marries normal male, and they have 4 kids. First 3 (two girls and a boy) are normal. Their 4th (a girl) has albinism like her mother. Include all genotypes and appropriate shading!
