Problem 4.19 Croaking in frogs is controlled by one gene with a pair of alleles

Question

Problem 4.19 Croaking in frogs is controlled by one gene with a pair of alleles - dominant uttering (R) and recessive muttering (r). Eye color is inherited by epistatic interaction of two genes with the following possible phenotypes: A_B_ - blue eyes; A_bb - purple eyes and aaB_ or aabb - green eyes. The frog geneticist mated two purple utteres with the following results: Part A 9/16 purple, utterers 3/16 purple, mutterers 3/16 green. utterers 1/16 green. mutterers What were the genotypes of the parents? AabbRr x AaBbRr AabbRr x AAbbRr AabbRr x AabbRr AAbbRr x AaBbRr AabbRr x Aabbrr AaBbrr x AabbRr

Explanation / Answer

As per the given results, the genotypes of the parents would be AabbRr crossed with AabbRr.

Hence, the correct option is AabbRr X AabbRr
