Amutation in a gene in the fruit fly drosophila was found to affect eye color. the protein affected was found to be completely normal in its molecular weight and amino acid sequence, although much less of the protein is made in mutant flies. the most likely reason for the change in levels of protein is that the mutation

1. variations in a population of moths allow for some of its members to be able to adapt to environmental changes. the better adapted of the moths will be able to survive the change and thus prevail as the “fittest” of the species. (a) describe three mechanisms in which variation can occur within a species population. (b) explain which mechanism or mechanisms would be responsible for the survival of a population of peppered moths better than white moths in an environment affected by industrial soot. justify your answer.
