Ideogram depicting the hybridization signals of chromosome sorts from eight placental mammal species (cat, elephant, horse, squirrel, pig, rabbit, ring tailed lemur, and tree shrew) onto human chromosome 1 (G-banded ideogram labeled at left). Colored blocks below each species name delineate the extent of hybridization observed for the chromosome paint probe on human chromosome metaphase spreads. The six species columns at left display new data, whereas the five species at right are taken from the literature as indicated. The numbers to the right of each colored block refer to the chromosomal origin of each probe from the examined species. For the lemur and elephant probes, the corresponding numbers of the flow karyotype peaks are given. The absence of hybridization signals in the heterochromatic region (Hsa1p11–Hsalq12) is indicated by the shaded bar.
