  1. The frequency of Jka gene is 0.52 and the frequency of the Jb gene is 0.48. What is the frequency of the Jk(a+b-)phenotype
    • p = .52 (Jka frequency)
    • p2 = (.52)2 = .27 or 27%
  2. In a given population, 16% of individual are tested as Rh negative. What is the gene frequency of the D gene?
    • q= dd = .16
    • √.16 = q = 0.4
    • p+q = 1
    • 1 - 0.4 = p = 0.6 is the gene freq for D
  3. A population of donors is tested for Fya and Fyb. Of the 1000 donors tested, 66% tested positive for the Fya antigen. What is the frequency of the FyaFyb genotype?
    49%
