Genetic and physical maps of md minimal interval. (a) Genetic map of proximal chromosome 16. Distances between markers indicated in centiMorgans (cM). (b) Mouse genomic clones spanning the minimal interval containing md. Distances indicated are in megabases (Mb). (c) Locations of all transcripts (identified by accession number) and predicted genes (all mCGs). Riken full-length cDNA AK011747 is the mahoganoid transcript (2,010 bp).
