6. About 70% of Americans get a bitter taste from the substance called phenylthiocarbamide (PTC). It is tasteless to the rest. The "taster" allele is dominant to non-taster. Also, normal skin pigmentation is dominant to albino. A normally pigmented woman who is taste-blind for PTC has an albino-taster father. She marries an albino man who is a taster, though the man's mother is a non-taster. 1 pt A. What are the genotypes of the woman and man? B. What phenotypes...
Phenylthiocarbamide (PTC) is an organic compound that either tastes extremely bitter or is tasteless, depending on the genotype of the taster. The tasting allele is dominant over the non-tasting allele. Normal skin pigmentation is dominant over albinism. (it is important to note that this example of PTC tasting cannot be explained with simple genetics, but for the purpose of this question, assume that it can) A normally-pigmented woman who cannot taste PTC has an albino father who can taste PTC....

I did 1-5 but confused on the rest LAB EXERCISE 4.1 continued Name 6 Remember that the ability to taste PTC is dominant to the inability. Two normally pigmented taster parents have an albino, taster son and a non-taster daughter with normal pigmentation. Using A and Tand a and t for the dominant and recessive alleles, respectively, create a Punnett square for two traits, as shown on pages 71-73 in the section "Transmission of Autosomal Traits: Two at a Time."...
