Answer:
a) The allele frequencies are -
b) Genotype frequencies for this population-
Explanation:
Given ,
Red color of flower is dominant to white color flower
Let "R" represents allele for red color and "r" represents allele for white color
out of flower, are red flowers.
So the frequency of red flowers with genotype "RR" is equal to
As per hardy Weinberg's I equilibrium equation -
a) The allele frequencies are -
Frequency of genotype "rr" i.e homozygous recessive white flower is
Substituting the values of and , in below equation, we get -
b) Genotype frequencies for this population-
