Question 6 of 10 1.0 Points
The same researcher (homozygous for Q allele) makes four conclusions from learning her genotype. Which one of these conclusions is WRONG?

A. She has two Q alleles in each somatic cell

B. She has only one Q allele in each of her gametes

C. Her parents must have been homozygous for the Q allele

D. She expects to pass on the Q allele to her offspring

Question 7 of 10 1.0 Points
Selection is LEAST likely to act against which type of mutation?

A. Nonsense

B. Non-synonymous

C. Synonymous

D. Frameshift


Question 8 of 10 1.0 Points
Some rat populations have become resistant to Warfarin (a plant-derived poison) after repeated exposure. If I want to study Warfarin resistance in a lab rat, can I make my rat evolve Warfarin resistance if I repeatedly expose it to small doses?

A. Yes, it appears to be a common mutation.

B. Probably, if it could survive long enough to cause the mutation it needed.

C. Cannot tell without more information

D. Unlikely, but possible only if the Warfarin gets into the somatic AND germ cells

E. No. One rat cannot evolve; only populations evolve.

Question 9 of 10 1.0 Points
Natural selection will always favor genotypes that:

A. produce the most offspring per parent.

B. have the largest and most vigorous offspring.

C. produce the greatest increase in survival.

D. have the most offspring that reach reproductive age.

Question 10 of 10 1.0 Points
Stabilizing selection increases the frequency of:

A. genotypes with fitness greater than the population average fitness.

B. any genotypes that have the same or very similar fitness.

C. genotypes with alleles that are 'fixed' so they have stable frequencies.

D. alleles that are incompletely dominant.

JUST need letter answer please.

Explanation / Answer

6) C. Her parents each needed at least once copy of Q but didnt have to be homozygous for Q. 7) C. Synonymous mutations are unlikely to affect function, so it is difficult to select between wild type and mutant. 8) E. No. One rat cannot evolve; only populations evolve. 9) D. have the most offspring that reach reproductive age. 10) A. genotypes with fitness greater than the population average fitness.
