Figure 4From: Genetic structure and mating system of wild cowpea populations in West AfricaAutocorrelation analysis. Autocorrelation analysis of wild-domesticated pairs of populations (r W-D ) performed on asymmetrical distance matrices. Plot of the genetic autocorrelation coefficient as a function of the geographical distance classes; dotted lines define the 95%-confidence interval based on 999 permutations.Back to article page
