Sample Problems using Hardy-Weinberg Equation 1. If you have a population (NOT in Hardy-Weinberg equilibrium) of 800 brown tree snakes, and 450 are homozygous dominant for brown belly scale color ( BB ), 320 are heterozygous ( Bb ), and 30 are homozygous recessive ( bb ). Calculate the allele frequencies for this population. B allele: ___________ b allele: ____________ 2. Now, calculate the genotype frequencies. BB _____________ Bb ______________ bb ________________ Is this population in Hardy-Weinberg Equilibrium? ____________ 3. In a population of Hobbits, with two alleles,

Unformatted text preview: R and r , for foot hairiness, the allele frequency of r is 0.3. What would be the frequency of heterozygotes if the population is in Hardy-Weinberg equilibrium? a. 0.49 b. 0.42 c. 0.09 d. 0.70 4. In a population of armadillos that is in Hardy-Weinberg equilibrium for two alleles, C and c, (which code for highway-crossing skills) 25% show a recessive trait (tendency to become roadkill). Assuming C is dominant to c , what percent show the dominant trait? a. 0.50 b. 0.25 c. 0.75 d. 0.125...
