Exam 4: Population Genetics and Natural Selection

Using microsatellite DNA, Douglas and Brunner concluded that populations of Coregonus found in the Alps were highly differentiated and should be managed as separate units.

________ can change population gene frequencies through random processes.

A type of selection that works to keep an average phenotype while reducing extreme phenotypes is called?

A population has a low V_G and high V_E. Which of the following statements are true for this population?

The Hardy-Weinberg principle states that

Within a population, if the average is selected for and the two opposing extremes are selected against, this is an example of

Heritability is defined as

Cheetahs have increased birth defects, reproductive defects, and disease due to

Adaptation to the environment by a population does not include

The alternate form of a gene is called a(n) ________.

Darwin is often considered the father of evolutionary thought. Which of the following terms is/are not part of Darwin's analysis?

Ecotypes are local populations within a species that are genetically and phenotypically distinct due in part to local environmental adaptation.

The transplant experiment conducted on Potentilla glandulosa determined that morphological changes occurred, but no genetic changes occurred within the various experimental populations.

The number of offspring contributed by an individual to future generations is called ________.

Populations of field crickets (Teleogryllus oceanicus) native to Australia, but now found on the Hawaiian islands have decreased genetic diversity when compared to source populations. This is a result of

Egg size in Ural owls is highly heritable and is currently undergoing stabilizing selection.
