SNP density plots by chromosome in REL line birds. The SNP density computed per 100 bp is plotted for the entire genome (GRCg6a) or each individual chromosome for male (solid) and female (hatched). GRCg6a is for the entire genome and MT is mitochondrial genome. The insert is a plot of SNP density by GC% for individual chromosomes (excludes mitochondrial genome)
