In one fishing village in Alaska, the allele frequency of webbed feet is 0.10. This dominant trait causes affected individuals to have extra skin between each of their toes on both feet. Assume that the village is the entire breeding population and that the population is in Hardy-Weinberg equilibrium. What is the frequency of individuals in this village that have webbed feet

Phenotypic frequency of the dominant trait = 0.19 ⇒ the frequency of individuals in this village that have webbed feet

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
