In a population of Mendel's garden peas, the frequency of the A allele (p) is 30% and the frequency of the a allele (q) is 70%. Of 100 plants, 28 are AA, 4 are Aa, and 68 are aa. Is the population in Hardy-Weinberg equilibrium? How can you tell?
What will be an ideal response?
No. The genotype frequencies are not those predicted from the allele
frequencies.
