Distribution of SNP index association values on chromosomes.

The abscissas indicate the chromosome names, the colored dots represent the calculated SNP index (or Δ [SNP index]) values, and the black lines represents the fitted SNP index (or Δ [SNP index]) values. The top figure shows the distribution of SNP index values of recessive pools; the middle figure shows the distribution of SNP index values of dominant pools; and the bottom figure shows the distribution of Δ (SNP index) values, where the red lines represent the confidence intervals. The threshold lines are equal to 0.99, the blue lines represent the threshold lines with a confidence level of 0.95, and the green lines represent the threshold lines with a confidence level of 0.90.
