Question

In a population of 100 poppies, 84 individuals have red flowers,while 16 have white flowers. Assume that white petals are inherited as a recessive trait(a) and red petals as a dominant trait (A). What are the frequencies q and p? In the next generation, whatwill be the equilibrium genotypic frequencies? Assume that white petals are inherited as a recessive trait(a) and red petals as a dominant trait (A). What are the frequencies q and p? In the next generation, whatwill be the equilibrium genotypic frequencies?

Explanation / Answer

p + q = 1 p2 + + 2pq + q2 =1 AA(homozygous dominant): p2 Aa or aA(heterozygous dominant): 2pq aa: homozygous recessive: q2 q2 = 0.16 q = 0.4 p = 1 - 0.4 = 0.6 Equilibrium genotype frequencies AA(homozygous dominant): p2 = 0.62 = 0.36 Aa or aA(heterozygous dominant): 2pq = 2 x 0.6 x 0.4 = 0.48 aa: homozygous recessive: q2 = 0.42 =0.16 Hope this helps!
