Question

Info you need to answer question: You are studying the enzyme alcohol dehydrogenase in a population of Drosophila. The allele frequency of the fast allele is 0.3 and the allele frequency of the slow allele is 0.7. Assuming the population is in Hardy Weinberg equilibrium what is the expected frequency of heterozygotes in the population?

Question 4 2 points Save Answer A large sa lefies from the population n quesion 2 is moved o a new habitat. There are no flies existing here. of the fast allele increases from 0.3 to 0.6. What evolutionary force is responsible for this result? There ls a lot more fermentng fruit and thus a o n this en ronment compared to the o igral environment. Over 10 generations the frequency evolutionary force is responsible for Mutation Migration Genetic drift Natural selection

Explanation / Answer

Answer:

Fast allele=p=0.3

Slow allele=q=0.7

Hardy weinberg equation

p^2+2pq+q^2=1

frequency of heterozygotes in the population=2pq= 2 x 0.3 x 0.7 =0.42 or 42%
