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 Nonwork
F1 generation All non workers of both sexes
To date you have obtained the following results:
P generation Hard worker x Nonwork
F1 generation All non workers of both sexes
You then mate an F1 female with a hard worker male and obtain the following offspring:
½ hard workers: ½ non workers of both sexes
From these results, predict the expected phenotypic ratio from crossing two F1 non workers.
