    Can anyone explain how to do hardy weinberg for this question http://www.ocr.org.uk/Images/58628-q...nvironment.pdf its 7cii
    Black = Dominant phenotype (p^2 and 2pq)
    Red = Recessive phenotype (q^2)

    Population size = 296 + 50 = 346

    To work out q^2 we divide the number of recessive phenotype individuals by the total number of individuals. 296/346. (Don't round it here as that could lead to mistakes later).

    q is just the square root of q^2 so square root 296/346 which gives 0.92
    p = 1 - q. 1 - 0.92 = 0.08.
