In a population of 1000 plants, the frequency of the a allele is 5 percent.Suppose a fire causes the loss of 500 individuals who are homozygous for the A allele.In this case the fire caused the frequency of a to change from ______ to ______.
A)5; 1
B)0.05; 1.0
C)0.05; 0.1
D)0.5; 1.0
E)0.5; 0.1

Initially, the frequency of the a allele is 0.05. After the fire, the remaining population consists of 500 individuals, and the frequency of a needs to be recalculated based on the new population size and composition. Since the fire removed individuals homozygous for A, the frequency of a increases to 0.1.
