Cross-Breeding Frogs to Determine if a Mutation is Dominant or Recessive...?

Question

There was a blue frog found, that you hypothesize to be the product of a recessive trait caused by a mutation in the regulation pathway of the gene which produces yellow pigment. What would be the most efficient mating experiment to test this hypothesis?

Answer 1

I guess I would have to say find another blue frog of the same species and mate the two blue frogs, two yellow frogs, and the blue frog and the yellow frog, kinda like how Mendel did with his pea pods. It would be exactly like that huh?

(but I'm not an expert just a tenth grader lol)
