Practice Problem # 2: The allele for free hanging earlobes (E) is dominant over the allele for attached earlobes. In a population of 10,000 individuals, 2,500 have attached earlobes. Determine the frequency of the dominant (p) and recessive (q) allele. How many individuals will be homozygous dominant (EE), heterozygous (Ee) and homozygous recessive (ee)? STEP # 1: Find the value of q, then use this value to find the value of p. ** (p + q = 1) ** p = q= STEP # 2: Plug in the values into the Hardy-Weinberg Equation.** (???????? + 2pq + ???????? = 1)** Homozygous Dominant = Heterozygous = Homozygous Recessive = Practice Problem # 3: The ability to taste the chemical PTC is controlled by a dominant allele (T). In a population of 5000 individuals, it was determined that 750 of the individuals were unable to taste PTC. Determine the frequency of the dominant (p) and recessive (q) alleles. How many individuals would you expect to be homozygous dominant (TT), heterozygous (Tt) and homozygous recessive (Tt). STEP # 1: Find the value of q, then use this value to find the value of p. ** (p + q = 1) ** p = q= STEP # 2: Plug in the values into the Hardy-Weinberg Equation.** (???????? + 2pq + ???????? = 1)** Homozygous Dominant = Heterozygous = Homozygous Recessive =
