Skin color appears to be controlled by several genes.This creates a continuum of variation) also seen inheight, hair color, etc.) If this polygenic explanationof the inheritance of human skin pigmentation iscorrect, how do the skin colors of the following fourindividuals compare? Which of the couples couldhave children with the widest range of skin colors?Why?Couple 1: aaBbCC and aaBbCCCouple 2: AaBbCc and AaBbCcLethal Genes: An allele that if present, results in prematuredeath. Lethal genes can be either dominant (heterozygotesor homozygous dominant will be affected) or recessive (onlyhomozygous recessive will die).17. When Mexican Hairless dogs are crossed withnormal-haired dogs, about half of the puppies are normal(have hair) and half are hairless. When two Mexican hairlessdogs are crossed, about 1/2 of the puppies are hairless, 1/4have hair, and 1/4 die before birth. Explain these results.Sex-linked traits: A gene is located on the sex chronmosomes
