There are two different phenotypes of a moth species, black and light grey, which are predated upon by birds. The more recently evolved black colour, is the dominant allele, B, while the recessive allele, b gives a light grey colour. Reduced pollution in the area has turned the trees (where the moths live) lighter. Which moth genotype(s) would be favoured by this change? Select one: O a. DD only O b. Dd only O c. dd only O d.
