Question

QUESTION 3 Vulcans have three genes, pointed ears (P), absent adrenal glands (A), and a right-sided heart (R) which are on the same chromosome, as shown below. The gene P is 10 map units from A. The gene A is 25 map units from R. All three of these alleles are dominant to normal Earth alleles: rounded ears (p), adrenal glands (a) and a left sided heart (r). P. (10 m.u.) A (25 m.u.) R Mr. Spock, the first officer of the starship Enterprise, has a Vulcan father and an Earthling mother. He also has pointed ears, absent adrenal glands, and a right-sided heart. If Mr. Spock marries an Earth woman, what is the probability that they will have a child with pointed ears, normal adrenal glands, and a right-sided heart? Show calculations for full credit.
