Question
1 -What is the term used to describe those individuals that have the recessive allele but do not exhibit the recessive trait?
2- In humans, having a "widow's peak" is a dominant trait. A man with a widow's peak marries a woman who does not have a widow's peak. All ten of their children have a widow's peak. What is most likely the genotype of the father (man)? W = widow's peak (dominant) w= no widow's peak
3- The ability to taste PTC (phenylthiocarbamide) is controlled by a dominant allele. Jim is a non-taster, who's parents can both taste PTC. Nancy is a taster. Nancy's father is also a taster, while her mother is a non-taster. What is the genotype of Nancy's father? T = taster (dominant) t = non taster

Explanation / Answer
Q1 What is the term used to describe those individuals that have the recessive allele but do not exhibit the recessive trait?
Answer: Heterozygous
Q2 In humans, having a "widow's peak" is a dominant trait. A man with a widow's peak marries a woman who does not have a widow's peak. All ten of their children have a widow's peak. What is most likely the genotype of the father (man)? W = widow's peak (dominant) w= no widow's peak
Answer : since widow's peak is a dominant trait , both homozygous and heterozygous individuals will express the trait. if the mother does not have widows peak (ww), the genotype of father should be homozygous dominant (WW), to produce all children with widows peak
Q3 The ability to taste PTC (phenylthiocarbamide) is controlled by a dominant allele. Jim is a non-taster, who's parents can both taste PTC. Nancy is a taster. Nancy's father is also a taster, while her mother is a non-taster. What is the genotype of Nancy's father?
Answer Genotype of nancy mother: tt (non tatster)
Genotype of nancy Tt (Taster)
GEnotype of anancy father (TT or Tt) , he is taster
