Problem: In a species of beetle, the allele for a shiny shell (C) is dominant to the allele for a dull shell (c), and the allele for horns (P) is dominant to the allele for a lack of horns (p). Consider a cross between CcPp and ccPP. What proportion of offspring do you expect to have the same genotype as either one of the parents?

O 1/4
