(c) If a pure long-nose person marries a person who has a short-nose, calculate the expected genotypes and phenotypes of their children.

Question 2: In humans there is a gene to taste phenylthiourea (PTU). 'Tasters' (TT or Tt) detect an extremely bitter taste, while 'non-tasters' (tt) detect no change or taste. If a person who is heterozygous for phenylthiourea marries a 'non-taster', what is the probability that their offspring will be 'non-tasters?
