Question

A population of butterflies has two alleles for color: blue alleles and green alleles. The blue allele is dominant. For each situation listed below, identify the mechanism of evolution at work. Select whether it is an example of natural selection, genetic drift, or gene flow. Fifteen green butterflies move into Drag answer here this population. natural selection genetic drift gene flow After a storm, by chance most survivors are green. Drag answer here Birds catch blue caterpillars more Drag answer here easily Green butterflies r escape from predators better. Drag answer here

Explanation / Answer

Gene flow

Gene drift

Natural selection

Natural selection

Note - change in allele frequancy occured dur to immigration or emigration is clled genetic flow while large change in allele frequancy due to destruction of population is called geentic drift.
