Give typing answer with explanation and conclusion The father of Mr Spock, first officer of the starship Enterprise, came from planet Vulcan; Spock’s mother came from Earth. A Vulcan has pointed ears (P), adrenals absent (A), and a right-sided double heart (R). All these alleles are dominant to Earth alleles. The three loci are autosomal, and they are linked as shown: --P----- 15 mu -----A-------- 20 mu --------R— Here's the new twist: having Vulcan adrenals and a human heart is an embryonic lethal combination, which will distort the proportion of the various phenotypes. If Mr Spock marries an Earth woman and there is no genetic interference, what proportion (0…1.0) of their children will have the phenotypes: A. Human ears, Vulcan heart, human adrenals B. Human ears, human heart, Vulcan adrenals C. Vulcan ears, Vulcan heart, Vulcan adrenals D. Vulcan ears, human heart, human adrenals
