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.

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...

5. Which of the following statements is true about the theory of evolution? The focus of the theory of evolution is to explain the origins of life. According to the theory of evolution, life evolved entirely randomly. The focus of the theory of evolution is to explain how life diversified from the first living cells. According the theory of evolution, only the strongest and toughest can survive. 6. Which of the following best explains our current understanding of microevolution? Neither...

INTRODUCTION
New mutations that arise on the X chromosome can have different
likelihoods of becoming fixed in the population than their
autosomal counterparts. This differential likelihood arises because
the effect of a recessive mutation on an autosome is only expressed
in homozygotes, whereas the effect of a similar recessive mutation
that arises on the X chromosome in a male is fully expressed. Thus,
advantageous recessive mutations are more likely to become fixed if
they are on the X chromosome than...
