SNPs and subspecific origin. Mouse Diversity Array SNPs (above) and subspecific origin (below) shown at a fine resolution. A high density of SNPs is represented as a histogram across the genome. As the user zooms in, the histogram's bar heights dynamically adapt to display the relative SNP densities in each genomic region. Individual SNPs are displayed as vertical ticks along the SNP track as the display resolution approaches an individual base-pair. Alleles for each strain are shown overlaying the subspecific origin to enable detailed analysis. Alleles are also shown overlaid on the haplotype track at low resolutions (not shown).
