A backyard homesteader that wants to expand the amount of cute duck breeds. They know the f gene codes for feather coloring (black feathers (F) are dominant to white feathers (f)) while the b gene codes for feet color (grey feet (B) are dominant to orange feet (b)). The homesteader crosses a super fertile heterozygous wild-type duck that has black feathers with grey feet (FfBb) with a homozygous recessive duck with white feathers and orange feet (ffbb). This produces 100 offspring.  2. Which are parental phenotypes? (2 answers)
