In a particular plant,two genes control leaf shape and color.Round leaves (R)are dominant to jagged leaves (r).Yellow fruits (Y)are dominant to white fruits (y).A true-breeding round-leaved,yellow-fruited plant is mated with a true-breeding jagged-leaved,white-fruited plant.What are the genotypes of the plants involved in this cross?
A) RRYY × RRYY B) RRYY × rryy C) RrYy × RrYy D) cannot determine from the information given
