Help with HardyWeinberg Equation?If about 35% of the human population has type "O" blood,
a) What must the frequency of the type O allele? b)what proportion of the populaton must be heterozygous carriers for type O?
Re: Help with HardyWeinberg Equation?We are using the equation p2 + 2pq + q2 = 1, where
p2 = homozygous dominant frequency 2pq = heterozygous frequency q2 = homozygous recessive frequency You should know that blood type O is recessive. Therefore, q2 = .35. Taking the square root of .35 will give you the frequency of the type O allele (q): sqrt (.35) = .592 Therefore, q = .592, and p = .408 (1  .592) In the HardyWeinberg equation, the frequency of heterozygotes is equal to 2pq. Therefore: 2 (.408) (.592) = .483 So, the proportion of the population that are heterozygous carriers is equal to .483 or 48.3%. Sorry for the late reply! I am new to the site!
