peppered moth

the moth Biston betularia, which has been extensively studied in many areas of Britain. Its coloration is of two main types: peppered (a mixture of white and grey) and melanic (dark brown), the relative proportion of the two colour types in an area being related to the amount of atmospheric pollution. The colour forms are an example of a GENETIC POLYMORPHISM controlled by a single gene with two ALLELES, the allele for melanism being dominant. see INDUSTRIAL MELANISM.

Hamadryas feronia may be considered a better example to explain the process of background selection than Biston betularia from Great Britain, because its natural history and taxonomy are well known and its behavior can be seen during daylight (Jenkins 1983, Monge-Najera & Hernandez 1991, Monge-Najera 1992, Monge-Najera et al.

The awakening of interest in this "alternative picture" in part reflects a sense that the paradigmatic cases of natural selection, such as industrial melanism in Biston betularia and heavy-metals tolerance in grass species, may not exemplify the process of evolution with respect to unexceptional environmental factors and less simply determined functional traits (Sultan 1987).
