160. The frequency for the allele for cystic fibrosis, an autosomal recessive trait, is 1 in 2500 among white Americans. What is the heterozygote frequency?
A) 8%
B) 4%
C) 1%
D) 10%
E) 14%
The answer is B because he uses 1 in 2500 to represent q^2. But if the question says the frequency of the ALLELE (not genotype) is 1 in 2500, I would think that equals equal q. The answer I got using this, 12.5% is not one of the answer choices, but regardless, can someone clarify? Or is this a Destroyer mistake?
