I'm having trouble answering this problem:
The ability to taste the chemical phenylthiocarbamide (PTC) is due to a
dominant gene (T) in man. The inability to taste PTC is due to its
recessive allele (t). A man who can taste PTC, but whose mother could
not, marries a woman who can taste PTC, but whose father could not.
What is the genotype of the man? Explain?
What is the wife's genotype? Explain?
What types of gametes will the man & woman produce?
What proportion of their children will probably have the ability to
taste PTC? _____ : ______
