Genetics and Hardy-Weinberg equation
Not what you're looking for?
4. In the Yucca plant, flower color is determined by a system of incomplete dominance. The genotype BB gives blue flowers, Bb gives lilac flowers, and bb gives white flowers. In a population of yucca plants, 8 had blue flowers, 84 had lilac flowers, and 52 had white flowers.
a. What is the frequency of the B allele in this population?
b. What is the frequency of the b allele in this population?
c. Based upon the Hardy Weinberg formula, what proportion of the population is expected to have lilac flowers?
d. Based upon the Hardy Weinberg formula, what proportion of the population is expected to be of genotype BB?
e. Based upon the Hardy Weinberg formula, how many individuals in this population would be expected to have white flowers?

Solution Summary
This abstract uses the example of flower color to illustrate how the Hardy-Weinberg equation can be used to calculate the frequency of a given allele within a population.
Solution Preview
In the Hardy-Weinberg formula, p(squared) is the frequency of the dominant allele, in this case 0.056 (8/144). Therefore p is 0.237. ...
