Homework Help: Biology

Posted by Kate on Sunday, July 4, 2010 at 2:44pm.

Iwas woudnering if you could help me with this problem. The answer key says that the answer is D and I have no idea why. The chart, included in the link, reads off a value of about .5 for the G locus for the year 1980

Finding the percent heterozygous should be as sipmle as 2(.5)(.5)=.5 I got .5 for g by simply taking the complement of the dominant trait G, gray, by doing 1-.5

Clearly I am doing something wrong. I do not know what I am doing wrong. Iw as woudnering if you could tell me the secret to this question as I can not get .67 for the life of me

Only 28% of the people who took this test got this question right and I can't figuer it out either...

h t t p : / / i m g 5 2 6 . i m a g e s h a c k . u s / i m g 5 2 6 / 4 6 7 7 / b i o f . p n g

Assuming that the population was in
Hardy-Weinberg equilibrium for the G locus, what percentage of the gray moths that emerged in 1980 was heterozygous?
(A) 0%
(B) 25%
(C) 33%
(D) 67%
(E) 100%
