Two related populations can mate with each other but don't because a mountain range separates them. What type of reproductive isolation does this describe? A. Temporal isolation B. Behavioral isolation C. Habitat isolation D. Mechanical isolation

Under what circumstances can two species with identical niches coexist indefinitely?

In a population, describe the result of inbreeding. Whether inbreeding leads to the change in the allele frequency. Explain the effect of inbreeding on the rare recessive alleles in the population.

How are species defined by the biological species concept? A. Populations of different species are not in the same small monophyletic group B. Individuals of different species cannot produce successful offspring C. Individuals of different species avoid inbreeding D. Individuals of different species have dissimilar morphologies O E. Individuals of different species hybridize and produce offspring that have high fitness

Is it better for an organism to maximize their direct fitness or their indirect fitness? a. Direct Fitness b. Indirect Fitness c. Trick question. Neither Direct or Indirect Fitness matter in evolution.

What is the term for organisms producing different phenotypes due to differences in the environment?    a. Genetic variation   b. Additive variation   c. Phenotypic plasticity   d. Reaction norm

Which one of the four forces of evolution has the smallest effect on changing allele frequencies?   a. Drift   b. Gene flow   c. Mutation   d. Selection

Would changes in the frequency of a gene in a population result in a new species? (yes or no) Explain your answer.

Which scenario accurately describes an example of artificial selection? A woman who worked hard to become a superior athlete has children who also turn out to be dedicated athletes. A scientist modifies the genes of a tomato plant to make it more resistant to disease. A seal living in a coastal region where food is abundant thrives and reproduces because of the abundance of food. A farmer intentionally breeds oranges to be more resistant to aphids.

Secondary contact after divergence rarely results in? A. creation of a hybrid zone B. formation of a new species C. the rapid decline of both populations D. extinction of one population
