Figure 4.

Pairwise plots of LD between PRNP alleles in U.S. cattle populations. Numbers refer to the physical location of polymorphisms in a PRNP consensus sequence file [GenBank:DQ457195] and the LD plots. Dark and light shading indicate high and low r2 values, respectively. Horizontal green bars highlight the region of high LD within PRNP that is flanked by polymorphisms at positions 449 and 7176.
