Differentiation and divergence between mitolineages for 1A^Z markers. Plots show F_ST values for a) females in the hybrid zone, b) males in the hybrid zone, c) females in pure populations, and d) males in pure populations; and D_XY values for e) females in the hybrid zone, f) males in the hybrid zone, g) females in pure populations; and h) males in pure populations. The x-axis shows marker position as mapped to Zebra Finch chromosome 1A. The markers in the black outlined box represent genomic region 1A^Z* (51–59 MB).
