Question

Which of the following are correct statements about a selective sweep of a beneficial mutation? (Select all that apply)

1. All else being equal, a higher selective advantage for the beneficial mutation implies that a longer haplotype will rise to fixation.

2. All else being equal, a higher recombination rate (r) in the chromosomal region around the selected locus implies that a longer haplotype will rise to fixation.

3.In sexual species, a selective sweep results in a reduction of nucleotide diversity throughout the entire genome, in a manner that is identical to the effects of a population bottleneck.

4. Following the completion of a selective sweep, neutral variation around the selected locus will return to normal levels in only a few (five to ten) generations.
