Title: Determine the percentage of people who are heterozygous for the trait. Post by: pineapplelove6 on Jul 22, 2014 In a large community of humans it is found that only 2% of the people do not have freckles (freckles result from a dominant gene). Determine the percentage of people who are heterozygous for the trait. Show your work.

Title: Re: Determine the percentage of people who are heterozygous for the trait. Post by: f_zah1 on Jul 22, 2014 This can be solved using Hardy-Weinberg theory.
f(no freckles) = q^2 = 2/100, so now find q Now, as p+q = 1, find p f(heterozygotes) = 2pq Title: Re: Determine the percentage of people who are heterozygous for the trait. Post by: pineapplelove6 on Jul 22, 2014 Thank you!
