From: Genome-wide divergence among invasive populations of Aedes aegypti in California
Genetic Clusters of Ae. aegypti based on PCA analysis. Principal Component Analysis based on the SNP data. Principal component 1 (PC1) accounts for 6.7% of variance and separates South Africa population (GC4) from United States (US) populations. PC2 accounts for 5.8% of variance and separates US populations into three groups (namely GC1, GC2 and GC3). PC3 further separates the Central California population into two groups (GC2 and GC3). PC4 separates the Southern California population from Exeter (Central California) and Vero Beach, Florida populations. PC5 and PC6 further divide the GC1 cluster separating Exeter, Garden Grove and Mission Viejo and Vero Beach samples
