Plutonian Tickle-bellies have a sex determination system just like mammals. Hairy Snout is a
holandric trait (carried on the Y chromosome). MyxRot, a handsome male Tickle-belly, has
lovely orange hair on his snout. He and his mate, OrgggWny, have six offspring, three boys and
three girls. Please answer the following questions about this family.
a. How many of MyxRot's and OrgggWny's offspring have hairy snouts? Can you predict
which ones?
b. Their eldest son, Bob, marries and has a son. What is the chance that Bob's son will also have
a hairy snout?
c. JoKchew, MyxRot's and OrgggWny's youngest daughter, marries a male who has a
smooth, hairless purple snout. She has eight offspring, each one lovelier than the last, and all
boys. What percentage of these offspring do you expect to have hairy snouts? Explain.
