Genome-wide analysis in chicken reveals that local levels of genetic diversity are mainly governed by the rate of recombination

Table 3 Percentage of genetic variation explained by six possible explanatory variables according to PLSR analysis of chicken diversity level in 1 Mb windows

	Red jungle fowl	Broiler	Layer	Common variation
recombination rate	6.30	6.16	4.48	6.34
divergence	(1.29)	(1.37)	3.62	2.06
gene density	3.02	2.91	2.93	3.31
GC content	3.12	(3.06)	(3.13)	3.48
d_S	(0.69)	(0.65)	(0.86)	(0.78)
d_N	(0.49)	(0.58)	(0.66)	(0.61)

Values in parentheses are for parameters that did not meet the p < 0.001 threshold in multi-linear regression.
