Grade 11 Biology Question

The ability to roll the tongue sideways (A) is dominant over theinability to roll one's tongue (a). In humans, non-attachedearlobes (B) are dominant over attached earlobes (b). Two parentswith attached earlobes can roll their tongues. They are bothheterozygous for the tongue rolling trait. What is the genotype ofthe mother? What is the genotype of the father? Whare are thepossible gametes from the mother? What are the possible gametesfrom the father? Draw the Punnett square, and combine the gametesto produce offspring. What is the phenotypic ratio of theseoffspring?
