Fig. 2. Correlates of ROH density variation across the genome.

Fig. 2

Runs of homozygosity (ROH) density, recombination rate and heterozygosity were quantified in non-overlapping 500 Kb windows, with each point representing one window. The top 0.5% of windows with the highest and lowest ROH density in the population, termed ROH islands (n = 24) and deserts (n = 24), are coloured in purple and yellow respectively in all four plots. a Relationship between ROH density and recombination rate. b Relationship of ROH density and SNP heterozygosity. c Recombination rate within ROH islands and deserts. d Heterozygosity within ROH islands and deserts. Solid lines in a and b are linear regression lines and dashed lines in c and d are genome-wide means. Boxplots show the median as a centre line with the bounds of the box as 25th and 75th percentiles and upper and lower whiskers as largest and smallest value but no further than 1.5 * inter-quartile range from the hinge.
