Questions from Genetics

Q: For the term genetic drift, what is drifting? Why is

For the term genetic drift, what is drifting? Why is this an appropriate term to describe this phenomenon?

Q: Why is genetic drift more significant in small populations? Why does

Why is genetic drift more significant in small populations? Why does it take longer for genetic drift to cause allele fixation in large populations than in small ones?

Why is G. tetrahit reproductively isolated from the other two species?

Q: Explain why the glucocorticoid receptor binds next to the core promoter of

Explain why the glucocorticoid receptor binds next to the core promoter of some genes, but not next to the core promoter of most genes.

A group of four birds flies to a new location and initiates a new colony. Three of the birds are homozygous AA, and one bird is heterozygous Aa. A. What is the probability that the a allele will beco...

Q: Describe what happens to allele frequencies as a result of the bottleneck

Describe what happens to allele frequencies as a result of the bottleneck effect. Discuss the relevance of this effect with regard to species that are approaching extinction.

Q: In genetics, what does the term population mean? Pick any

In genetics, what does the term population mean? Pick any species you like and describe how its population might change over the course of many generations.

With regard to genetic drift, are the following statements true or false? If a statement is false, explain why. A. Over the long run, genetic drift leads to allele fixation or loss. B. When a new mu...

Q: When two populations frequently intermix due to migration, what are the

When two populations frequently intermix due to migration, what are the long-term consequences with regard to allele frequencies and genetic variation?

Q: Two populations of antelope are separated by a mountain range. The

Two populations of antelope are separated by a mountain range. The antelope are known to occasionally migrate from one population to the other. Migration can occur in either direction. Explain how mig...
