Polyploidization, both ancient and recent, is frequent among plants. A “two-step theory" was proposed to explain the meso-triplication of the Brassica “A" genome: Brassica rapa. By accurately partitio
1Sites with missing or ambiguous information in the outgroup were excluded from this analysis. L, number of nucleotides of the multiply alignment region; S, number of segregating sites; R, population
All estimates exclude singletons observed in the sequences from wild rats. Tajima's D = Results of Tajima's D test. Fu & Li's D = Results of Fu & Li's D test with outgroup. Fu & Li's F = Results of Fu
Identifying regions of the human genome that have been targets of natural selection will provide important insights into human evolutionary history and may facilitate the identification of complex dis
