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

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

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

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

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

This occurs when 2 populations can no longer interbreed

What does this image represent?

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

All of the genetic information (all of the alleles) found in a population.

Florida panthers used to be more numerous in the Everglades. Today, there are only a few hundred left in the wild due to habitat loss and cars. Numbers are slowly recovering. Which genetic drift is this?

The process in which one species splits into two or more species

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?

There are two types of genetic drift, founder effect and the ________________ .
