The fruit fly allows for the examination of one way that foraging behavior might have evolved. variation in a gene called forager (for) dictates how far drosophila melanogaster larvae travel when foraging. on average larvae carrying the forr ("rover") allele travel nearly twice as far while foraging as do larvae with the fors ("sitter") allele. how might the inheritance of these alleles impact the survival (fitness) of fruit flies? explain.
