In apples, the allele a is dominant for a big size apple and the allele r is dominant for red color. you cross one tree that produces big yellow apples and another tree that produces small red apples. half of the offspring trees produce big red apples and half produce big yellow apples. what are the genotypes of the parents?

AArr and aaRR
