Figure 3From: Strong reproductive barriers in a narrow hybrid zone of West-Mediterranean green toads (Bufo viridissubgroup) with Plio-Pleistocene divergenceGenotype-based assignment of Sicilian green toads based on Bayesian cluster analyses. Bar plots from the program Structure based on seven microsatellite markers for green toads coming from Sicily for K = 2. Population 25 represents F1-hybrids coming from a laboratory cross between one female B. balearicus (pop. 11) with a male B. siculus (pop. 22).Back to article page
