Based on the data provided, the frequency of heterozygous bats within the population is 0.32
Allele frequency can be defined as the frequency in which a given allele for a gene occurs in a population.
Allele are alternate copies of a gene.
Alleles can be either dominant, recessive or co-dominant.
The allele frequency is given by the Hardy-Weinberg equilibrium equation given below:
For the vampire bats:
p = 0.2
then; q = 0.8
p^{2} = 0.04
q^{2} = 0.64
The frequency of heterozygous bats within the population = 2pq
2pq = 1 - (0.04 + 0.64)
2pq = 0.32
Therefore, the frequency of heterozygous bats within the population is 0.32
