The ideogram (in blue) shows average chromosome lengths, positions and sizes of DAPI-positive (heterochromatin) bands. The percentage of heterochromatin reflects the time of appearance of heterochromatic bands (100% observed in all preparations; lower percentages seen only in early prophase spreads). Lines to the right of chromosomes represent BACs shown by FISH to bind in relative order and positions predicted from the genetic and physical maps. Binding sites of rDNA probes (distal short arms of chromosomes 6 and 12) are shown in red. The karyotype (below the ideogram) is based on the rightmost spread.
