The inability to taste phenylthiocabamide (PTC) depends upon an autosomal recessive gene (t), while the ability to taste PTC is due to its normal alternative (T). A man zygous for the ability to taste PTC marries a woman who cannot taste PTC, what is the phenotype and genotype of their F1 progeny? What is the phenotypes, genotypes and their ratios of the offspring if this F1 marries an indivudual who is a non-taster for PTC? What is the phenotypes, genotypes and their ratios of the offspring, if two F1s marry.
