You are working with the exotic organism Phobia laboris and are interested in obtaining mutants that work hard. Normal phobes are lazy. Perseverance finally pays off and you successfully isolate a true-breeding line of hard workers. You begin a detailed genetic analysis of this trait. To date you have obtained the following results: P generation Hard worker x Nonworker F_1 generation All nonworkers of both sexes You then mate an F_1 female with a hard worker male and obtain the following offspring: 1/2 hard workers: 1/2 nonworkers of both sexes From these results, predict the expected phenotypic ratio from crossing two F_1 nonworkers.
