Markers segregation distortions along the genetic maps. On the y-axis the negative log10 of p-values in chi-square tests (−log10(p)) comparing segregation frequencies of the alleles of the SNP retained in the genetic maps of ‘Shavtsitska’ (blue) and ‘Glera’ (red). The higher values for ‘Glera’ chr 13 demonstrates the presence in the LG of significant segregation distortions from the expected Mendelian ratio of 0.5 (e.g. a -log10(p) value of 2 corresponding to a p-value of 0.01). Vertical grey breaks are positioned every 30 cM on the LG of the genetic maps
