SHORT QUESTIONS

 

Short answers can be a paragraph, but answers need to be on point.

1. Explain how does inbreeding increase the risk of extinction for a population.

2. For a population undergoing exponential growth, if its exponential growth rate (r) is 0.3148, what is its geometric growth rate (λ)? If the population size (N) is 2500 individuals, what is the rate of change of the population? Show all of your work.

3. Explain the differences between primary sexual characteristics and secondary sexual characteristics. Give an example of each.

4. For a population undergoing geometric growth, if its geometric growth rate (λ) is 2.07 and its initial population size (N0) is 863 individuals, what would the population size be after five generations? What would its geometric growth rate be after five generations? Show your work.
