Distribution of polymorphic SNP within chromosomes. Bin size: 10 Mbp. Bin colors indicate significant non-uniform distribution of SNPs (see text). Red: over-representation of polymorphic SNPs; Blue: under-representation of polymorphic SNPs. Thick boxes indicate bins containing the annotated centromeres; green vertical bars denote bins containing the introgressed QTL; grey rectangles indicate incomplete terminal bins (excluded from tests).
