Comparison of mouse and human physical maps. A mouse recombinational map based on 1154 meioses (Reeves et al. 1997) is shown (top), spanning 3.5 map units with 16 markers at nine loci. Mouse and human physical maps are shown with the positions of transcripts indicated by a horizontal line beneath the marker name. Where gene orientation has been determined, an arrowhead indicates the direction of transcription. The consensus human physical map was compiled from several sources (Burmeister et al. 1991; Chumakov et al. 1992; Ichikawa et al. 1993;Dufresne-Zacharia et al. 1994; Patil et al. 1994; Gardiner et al. 1995;Gosset et al. 1995; Korenberg et al. 1995; Cabin et al. 1996; Osoegawa et al. 1996; Hubert et al. 1997; Ohira et al. 1997). With the exception of D21S15 and D21S349, the markers shown above the scale bar are known transcripts. Five NotI sites are shown beneath the map; LB23T and LB7T are separated by ∼30 kb. Gene 1131127 matches sequence from LL42SP.Where coding sequences on the human map are well localized, a horizontal bar is shown beneath the marker name. Less well-localized markers are placed in their approximate position without a horizontal bar.
