The difference in GC-content between the Z sequence and W sequence (Y axis) plotted against the sequence divergence (X axis) of common whitethroat gametologs. The panels show the Z-to-W GC-content and degree of functional divergence (dN) for (a) the neo-sex chromosome and (b) the ancestral sex chromosome, and non-functional (dS) divergence for (c) the neo-sex chromosome and (d) the ancestral sex chromosome.
