Numbers of EST (expressed sequence tag) assemblies and the corresponding independent loci mapped on the pig genome are shown for each chromosome. “Forward” and “Reverse” indicate that the assemblies were aligned on the chromosomes in the orientation from pter to qter or from qter to pter, respectively.
