Mr. Spock's father came from the plant Vulcan and his mother was from planet Earth. A Vulcan has pointy ears and a heart on the right side of the body. Earthlings have round ears and a heart on the left side of the body. Spock has decided to follow in his father's footstep and marry an Earthling. What is Spock's genotype? What is Spock's wife's genotype? What percentage of their offspring would have the same phenotype as Spock? Pointed ears and heart on the right are dominant (you choose the representative letters).
