A new study published in the journal Scientific Reports has revealed the strongest evidence to date that all bison in North America carry multiple small, but clearly identifiable, regions of DNA that originated from domestic cattle.
In the study, Texas A&M University College of Veterinary Medicine & Biomedical Sciences (CVMBS) researchers, led by James Derr and Brian Davis, compared genome sequences among the major historical lineages of bison to 1,842 domestic cattle, establishing that all analyzed bison genomes contained evidence of cattle introgression.
