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.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
