The ability to taste certain substances, such as PTC is also genetically controlled. People that can taste have a dominant allele (T), while non-tasters have the recessive alleles (tt). Suppose a woman who is a non-PTC-taster has offspring with a man who is a nomozygous PTC taster. What is the probability that hey have a child with the tasting gene? A25% e50% ©75% O 100%
