In almond trees, the allele A = big almonds and a = small almonds; the allele B = bitter almonds; b = sweet almonds. You have one tree that produces only big bitter almonds and another tree that produces only small sweet almonds. When the two are crossed, you find that half of the offspring trees produce big bitter almonds and half produce big sweet almonds. What are the genotypes of the two parents? Hint: You need to determine exactly what the genotypes of the parents were so that when they were crossed, 50% of their offspring were big and bitter and 50% of their offspring were big and sweet.
