If there is a mutation occurring in a population that turns allele "A" into allele "a" (and no other mechanisms of evolution are at work in the population), which of the following will be true? Allele frequencies will stay the same over time The frequency of "A" will increase over time The frequency of "a" will increase over time We can't tell what will happen to the allele frequencies in the population, given this information.

If the average excess fitness for individuals possessing a specific allele is positive, what is the expected change in the frequency of that allele in the population due to selection? A. The allele should increase in frequency if it is currently at a frequency greater than 0.5 and decrease in frequency if it is at a frequency less than 0.5. B. The allele should increase in frequency. C. The allele could either increase or decrease in frequency depending on the average fitness of the population. D. The frequency of the allele should remain the same.

In this large, isolated population, the frequency of the dominant allele, A, is 0.5 and the frequency of the Recessive allele, a, is also 0.5. Assuming that mating is random and no selection or mutations are occurring what will happen to the "allele frequencies (p and q) at the end of 5 generations? (ie: will one allele increase or decrease) Prediction: Reason:

In general, if a small natural population inbreeds for many generations, what will happen to the frequency of deleterious alleles over time? The frequency will remain the same. No answer text provided. The frequency will increase. The frequency will decrease.
