Idiograms for rat RNO 1, 8, and 20. The left-side block indicates the chromosomal linkage map derived from the GK×BN intercross; the central block indicates the chromosomal physical map. The lines between these two blocks represent the genetic position of a microsatellite and its physical position as determined by e-PCR. The right-side blocks indicate the suggested respective homologous segments of the mouse genome, with the white trapeziums indicating the ends of the mouse chromosomes. The lines on the right side of the figure indicate the comparative mapping of ESTs between the rat and mouse genomes as determined by BLAT searches. Cat's-cradle patterns identify intrachromosomal rearrangements between the two genomes.
