Bos taurus haplotypes segregating in Nellore (Bos indicus) cattle

open access: yesAnimal Genetics, 2021
SummaryBrazil is the largest exporter of beef in the world, and most of that beef derives from Nellore cattle. Although considered a zebu breed (Bos indicus), the history of Nellore cattle in Brazil is marked by the importation of bulls from India, the use of a Creole taurine (Bos taurus) maternal lineage to quickly expand the herds and backcrossing to
