If a population evolves a higher mutation rate, how will this affect evolution?
A. More mutations will be available faster
B. Selective sweeps will occur more quickly
C.this will have no effect on evolution
D. If the population size is very large, the mutation rate has no effect on mutation supply
Homework Answers
If a population evolves a higher mutation rate, higher incidence of harmful mutations in the average population fitness will decrease. If the mutations are occurring at random, the average fitness in a population increases despite a high mutation rate. Hence, option D is correct.

Mutations are the ultimate source of genetic variation. However, they usually occur at very low frequency. Assume a mutation resulting in a novel allele occurs in a gene of one individual in a population of 500 diploid individuals. The allele does not affect the fitness of the individual carrying the mutation. How long will it take for the allele to reach a frequency of 0.5 in the population? A. It cannot reach a frequency of 0.5. It will eventually reach...

Q3.3. Recall the prediction: Allele frequencies change by genetic drift equally quickly in large populations and in small populations. Is this correct? Why or why not? Yes. Genetic drift is sampling error, and sampling error is unpredictable, no matter the population size. Yes. Small populations experience more sampling error, but large populations have more reproduction overall, leading to similar rates of allele frequency change. O No. In the ferret experiments, allele frequencies changed more quickly in the small populations than...

Consider a mutation in tubulin that alters how tubulin changes its conformation after GTP hydrolysis. More specifically, the mutation makes tubulin "stiffer" after GTP hydrolysis, such that the tubulin does not transition as quickly between the straight and curved conformations. How would microtubule dynamics be affected by this mutation? Select all that apply. Question 5 options: a) Microtubules will grow faster (the net growth rate increases). b) Microtubules will shrink more slowly after a catastrophe (the "post-catastrophe shrinkage rate" is...

If most mutations are not strictly neutral but rather slightly deleterious, which of the following will be a consequence (select all that apply) A. A larger population will result in a smaller effectively neutral mutation rate. O O B. Molecular clocks will tick more accurately when measured in substitutions per year rather than substitutions per generation. C. The level of polymorphism in natural populations could be explained by balancing selection. D. Even very large populations will have heterozygosities less than...
