Title: Which of the following genotype frequencies of AA, Aa and aa respectively satisfy the Hardy Weinberg principle? Post by: Lexie on Sep 14, 2012 All of the answers add up to 1, so that condition is satisfied. The other question is whether or not if p and q are calculated, then p + q = 1:
a. AA 0.36 Aa 0.55 aa 0.09 so, p = 0.6, so q should equal 0.4, however, 0.4^2 = 0.16, not 0.09, so a is wrong b. AA 0.49 Aa 0.42 aa 0.09 so, p = 0.7, so q should equal 0.3, so q^2 = 0.09 and 2pq = 2 x 0.7 x 0.3 = 0.42 so b is correct c. AA 0.64 Aa 0.27 aa 0.09 so, p = 0.8, q = 0.2, so q^2 should equal 0.04, not 0.09, so c is wrong d. Aa 0.29 Aa 0.42 aa 0.29 p = SQRT(0.29) =0.5385 since p not equal to 0.5, then p cannot equal q and so q^2 cannot equal 0.29, so d is wrong. So, I would choose answer f, none of the above, since only b is the correct answer. |
