WebSTEP 1: Start with the leftmost tip and note the alleles present at the B locus. The haplotype at this tip is A1/b, since the ancestral chromosome carried the "b" allele and no mutations have occurred at the B locus along this lineage. STEP 2: Move on to the second tip from the left and note the alleles present at the A locus. WebUnder recurrent sweeps, the frequency spectrum is skewed toward rare alleles. However, the excess of high-frequency derived alleles, previously shown to be a signature of single selective sweeps, disappears with recurrent sweeps. It is shown that, using this approximation and multilocus polymorphism data, genomewide parameters of directional ...
