Fig. 2From: Physical mapping and candidate gene prediction of fertility restorer gene of cytoplasmic male sterility in cottonThe distribution of SNP-index-associated values on chromosome. Note: The abscissa is the chromosome name. The color point represents the calculated SNP-index (or ΔSNP-index) value, and the black line is the fitted SNP-index (or ΔSNP-index) value. The top graph illustrates the distribution of the SNP-index values in h mixed pool; the middle graph is the distribution of the SNP-index values in L mixed pool; the bottom graph is the distribution of the ΔSNP-index values, where the magenta line represents the theoretical threshold lineBack to article page
