Question 9

In a woodland population of the peppered moth (Biston betularia), 84% of the moths have the melanic (dark) phenotype. The allele for the melanic phenotype ( $M$ ) is dominant over the allele for the typical (light, speckled) phenotype ( $m$ ).

Use the Hardy–Weinberg equation to calculate the percentage of moths in this population that are heterozygous ( $M m$ ) for this gene.
