Coverage depths of genes on the <i>M</i>. <i>picta</i> sex chromosome and an autosome.

In each part, the y axis shows estimated normalized coverage values and the x axis shows physical positions in the guppy reference assembly of the homologous chromosome. In both the guppy and M. picta, chromosome 12 is the sex chromosome, and LG15 is shown as a representative autosome (as explained in the text, other autosomes are similar). The red horizontal line indicates a value of 0.5, as expected for hemizygous genes, and the blue one indicates diploid coverage (a value of 1), as seen for most genes across the autosome, and for two clusters of LG12 genes.
