Fig. 2From: Population genomics reveals that an anthropophilic population of Aedes aegypti mosquitoes in West Africa recently gave rise to American and Asian populations of this major disease vectorGenetic structure in Ae. aegypti populations. a Principal component analysis of Ae. aegypti exome sequences from five populations. The PCA was calculated from a covariance matrix calculated from all variants in the genome while accounting for genotype uncertainty. The percentage of the variance explained by each component is shown on the axis. b Ancestry proportions for Ae. aegypti individuals from five populations. Ancestry is conditional on the number of genetic clusters (K = 2–5) and is inferred from all sites in our datasetBack to article page
