Actually, since you know that q=.55 and p=.45, you can calculate that p^2=.2, q^2=.3, 2pq=.5. So, to figure your percentages out of 970 people, it would be: (970*.5)+(970*.2)=679. You can check this by multiplying 970*.3=291. 291+679=970. So, there would be 679 tasters...

Since both parents are tasters, the dominant phenotype, they each could be homozygous dominant (TT) or heterozygous (Tt). So when you set up the Punnett squares you need to set up three of them. One...

I have to chuckle a little bit. This is two nights in a row with the same question. Here's the answer: D. We know that if frequency is 50% (everybody is a carrier), then 25% of their posterity will express the recessive trait. You...

D. We know that if frequency is 50% (everybody is a carrier), then 25% of their posterity will express the recessive trait. You are looking for something that would produce 30% (slightly greater than 25%), so D, or 55% makes sense. Also...

Hardy-Weinberg equilibrium= (p2) + (2pq) + (q2) = 1 f(AA)= p² f(Aa)= 2pq f(aa)= q² ------------------------- q²=0.3 q= 0.54 (p2) + (2p*0.54) + 0.3 = 1 p² + 1.09p= 0.7 p*(p + 1.09) =0.7 p=0.7 or p + 1.09=0.7 p= - 0.39 (a frequency cannot be negative, so the answer...

This is the third time this question has been posted. Here is the answer: D. It's my best guess. We know that if frequency is 50% (everybody is a carrier), then 25% of their posterity...

Looks like this got double posted. Here is my answer again: D. It's my best guess. We know that if frequency is 50% (everybody is a carrier), then 25% of their posterity will express the recessive trait...

q^2 = 0.3 Recessive allele refers to just q. So, take the square root and voila, youre done.
