Let's work an autosomal problem. In fruit flies the wild type of eyes is red and it is dominant. The mutant eye color is scarlet and it is recessive. 1. A male fruit fly has scarlet eyes, what has to be his genotype? 2. A female is a carrier of the scarlet eye mutation, but does not exhibit the phenotype, what is her genotype? 3. What would be the phenotypes and genotypes of the predicted offspring? 4. In what percentage would you expect to find each phenotype and genotype?
