I . DETERMINING THE MODE OF INHERITANCE OF GREEN EYES IN MUTANT1 Reciprocal Cross 1A: Wild-type Female x Mutant1 Male

You are studying the mode of inheritance of eye color in flies. You have isolated four true-breeding mutant strains with green eyes . In contrast, wild-type flies have red eyes . In your Strains box in StarGenetics you will find 1) homozygous mutant male and female flies for each mutant strain and 2) homozygous wild-type male and female flies. In each of the four mutant strains, the mode of inheritance underlying the green-eye phenotype is DIFFERENT. You will use StarGenetics to determine amongst the four modes of inheritance listed above for green eyes in EACH mutant strain by performing the same series of tasks. Below is a summary of the tasks you will perform for each mutant strain. The following page contains detail instructions of how to perform each cross in StarGenetics.
