Hey I was wondering if I could get some help on some hardy Weinberg equilibrium problems. Choose from A,B,C,D, or E. Thanks!
1. If a population that contains 16% homozygous recessive individuals (blue eyes) and 84% individuals with brown eyes (homozygous dominant and heterozygotes), what is th frequency of the dominant allele in the population?
A. 0.6 B. 0.4. C. 0.32 D. 0.64 E. 0.8
For questions 2-3: in a certain flock of sheep, 4 percent of the population has black wool and 96 percent has white wool. Assume that the population is in Hardy-Weinberg equilibrium.
2. If black wool is a recessive trait, what percentage of the population is heterozygous for this trait?
A. 4% B. 20% C. 32% D. 64% E. 80%
3. What percentage of the population is homozygous for white wool?
A. 20% B. 40% C. 64% D. 80% E. 96%
4. The genotype frequencies for the black hair locus are 25% homozygous dominant (BB), 71% heterozygous (Bb), and 4% homozygous recessive (bb). this information shows that
A. The dominant phenotype is less fit
B. There may be a heterozygous advantage
C. The recessve allele will disappear in a few generations
D. The population is not in Hardy-Weinberg equilibrium
E. Individuals with the homozygous dominant genotype produce more offspring.
