15. The following pedigree shows inheritance of Huntington's disease, a fatal genetic
disorder that causes neurodegeneration. Since signs and symptoms usually do not
appear until adulthood, many who are carriers may not realize their risk of passing on
the disease-causing allele. The following pedigree represents a family in which some
people are affected by Huntington's disease.

- 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 adrenalsarrow_forwardA.
