Reggie owns a flower shop. He has a species of flowers, Flora spottist, that can grow in three form: yellow flowers (YY), blue fowers (BB), or flowers with yellow and blue spots (YB). Yellow and blue spots are the result of a heterozygous co-dominant trait.
Reggie’s notices that solid yellow Flora spottist are more popular than the other types, but Reggie only has one yellow flower plant. If Reggie wants to grow more yellow flowers plants, which parents should he choose if he wants the most yellow plants?
