Figure 5From: Travelling in time with networks: Revealing present day hybridization versus ancestral polymorphism between two species of brown algae, Fucus vesiculosus and F. spiralisMicrosatellite detection of admixture (introgression) using the program STRUCTURE (Pritchard et al., 2000). Each individual is represented in the figure by a vertical bar and its colors indicate the proportional membership in each of k = 2 clusters, thereby providing a quantitative illustration of introgression. Red represents F. spiralis, green F. vesiculosus.Back to article page
