## Description

This track shows exon-anchored orthologous blocks for the $organism assembly and the chimp assembly (Nov. 2003 - panTro1), taken from a 5-species orthology map (chicken, human, chimp, mouse, rat). The map is 1-to-1 and symmetric, so segment IDs are common to all pairwise tracks generated from the map. See http://hanuman.math.berkeley.edu/~cdewey/homologyMaps/ for an outline of the methods used to produce the map.
