The pedigree is for a monogenic trait (controlled by a single gene). Is the trait of interest (filled in shapes) encoded by a dominant allele or a recessive allele? Explain your answer in one or two sentences: For the mating within the dashed box in the pedigree, fill out the punnett square above that represents the alleles associated with this cross (Use any letter you want for the alleles, but make the dominant allele a capitol letter and the recessive allele a lower case letter).
