    0.87

    Explanation:

    As given

    q=red (recessive)

    p=purple (dominant);

    According to Hardy-Weinberg law;

    (p+q) = 1 = p² + 2pq + q²

    As the information provided, the red allele is recessive and it is represented by q

    so q² = 76/100 = 0.76

    Now we can find the recessive allele frequency using it as q is the frequency of recessive allele.

    Thus, q = √0.76

    q = 0.8717797887

    Thus, the value of q is 0.871
