    In this given pedigree what is the mode of inheritance

  • Question 3/10
    4 / -1

    In a random mating population frequency of recessive allele is 0.7. What will be the frequency of dominant phenotype ?

    Solutions

    q = 0.7 so, p = 1 – q = 1 – 0.7
    = 0.3 
    dominant phenotype = p2 + 2pq
    = (0.3)2 + 2 × (0.3) × (0.7) 
    = 0.09 + 0.42 = 0.51
