Any change in the genetic material (DNA) of a cell is called a

Suppose a sea mount (little island in the ocean) forms from an underwater volcano. Birds from the mainland happen to colonize the island and no longer interbreed with the original population due to distance. What type of isolation?

Natural selection acts directly on (genotype/phenotype) - choose one

A group of organisms that can mate with each other and produce fertile offspring are called a

True/False: Genetic drift is change in the allele frequency of a population due to a random, chance event.

A trait that is controlled by two or more pairs of genes

When members of a population become a new species due to having different courtship rituals (singing, dancing, etc...) , this is called __________ isolation.

Temporal isolation occurs when two different parts of the population reproduce at different _______________ .

This is a mechanism of evolution in which allele frequencies of a population change over generations due to chance, NOT fitness

In this type of natural selection, individuals with intermediate traits (the average/middle) are more likely to survive and reproduce

What does this image represent?

The frequency of phenotypes for a typical polygenic trait is most often shown as
