All estimates (mean ± SD) from the MCMC methods are summarized from the second half of 2000 iterations.
↵^{a} Initial values for MCMC (±SD): run 1, θ= 3.0 (±0.1), λ_{X} = 0.03 (±0.001), λ_{3} = 0.01 (±0.0005), γ_{2} = 3.0 (±0.1); run 2, θ= 1.5 (±0.15), λ_{X} = 0.035 (±0.0015), λ_{3} = 0.005 (±0.0015), γ_{2} = 3.5 (±0.15); run 3, θ= 1.0 (±0.1), λ_{X} = 0.01 (±0.001), λ_{3} = 0.035 (±0.001), γ_{2} = 3.5 (±0.1).
↵^{b} The MCMC simulations are run separately for observations from the X (X) or the third (3) chromosomes or jointly (X and 3).
↵^{c} S_{X}(½), the estimated number of hybrid male semisterility equivalents on the X chromosome, calculated as λ_{X}L_{X}/θ, where L_{X} (= 981) is the polytene band count on the X chromosome. S_{X}(1), the estimated number of hybrid male full-sterility equivalents on the X chromosome, calculated as λ_{X}L_{X}/θ/γ_{2}. S_{3}(½) and S_{3}(1) are similarly calculated with L_{3} = 2200.
