Genome-wide distribution of SNPs and genetic variants throughout the Ye478 and Qi319 genomes. The outermost box with scale represents the 10 maize chromosomes. The orange histogram represents the density of SNPs that are polymorphic between Ye478 and Qi319; the green histogram represents the density of polymorphic SNPs within coding sequences between Ye478 and Qi319; the blue histogram indicates the density of insertions or deletions (Indels) between Ye478 and Qi319
