Zaphod, a space alien from a planet near the star Betelgeuse, meets and marries a phenotypically normal Earth woman, Jane. Interestingly, Zaphod himself has a father from his home planet and a human mother. Aliens from the Betelgeus region like Zaphod have pointed noses (specified by allele Q), purple ears (specified by B), and extra-long arms (specified by S). All three alleles are dominant to corresponding wild-type Earth alleles. The three gene loci are located on autosomes. The three genes are known to have the linkage arrangement where gene B is in the middle of Q and S with the Q-B distance equal to 15 mu and the B-S distance equal to 20 mu. If Zaphod and Jane have children, and there is no genetic interference, what proportion will have: A] Alien phenotypes for nose, ears, and arms? (1 mark) B] Earth phenotypes for nose, ears, and arms? (1 mark) C] Alien nose and arms but Earth ears? (1.5 marks) D] Alien nose, but Earth arms and ears? (1.5 marks)
