Fig. 2From: Wide prevalence of hybridization in two sympatric grasshopper species may be shaped by their relative abundancesThreshold value for the correct hybrid assignment in STRUCTURE. In total 800 hybrids (200 per hybrid class, F1, F2, Backcross with Ch. montanus = Bmon; Backcross with Ch. parallelus = Bpara) were simulated with HYBRIDLAB 1.1 [51] using purebred individuals from a previous analysis (119 Ch. montanus, 118 Ch. parallelus). Afterwards the STRUCTURE run was performed with 105 MCMC and a burn-in period of 104 chains (with 10 iterations for K = 2)Back to article page
