After performing a series of breeding experiments the naturalist sets up a mating between some pure breeding red and a pure breeding yellow lizardos. Of the 100 F1 offspring that hatch 73 lizardos are red while 27 lizardos are yellow. Choose a letter to represent this gene. Fill in the Punnett square to illustrate the expected outcomes (not numbers just the letters) if a yellow lizardo were mated with a red lizardo from the F1 generation.
