Simple Genotype Frequency Calculation
What is the frequency of the Aa genotype and the AA genotype if the frequency of allele A is 0.9%?

p = 0.9
q = 0.1 prevalence of Aa genotype is 2pq = 0.1 prevalence of AA genotype is p^2 = 0.81

How did we calculate q to be 0.1?

#6




I sat for a while, trying to remember how to do quadratic equations!

#7




isn't its more close to .2 than .1?

To use the p2 + 2pq + q2, it has to be in equilibrium. How would you just assume that the population is in hardy weinberg equilibrium ? Although I'm pretty sure that this is the way to calculate it ...

Isn't the this is the case unless otherwise mentioned ?

Yeah it should be 0.18 = 2pq = Aa

#11




Yeah, 0.18, my bad. Left out the 8 =/
