Novel insights into the bovine polled phenotype and horn ontogenesis in Bovidae.
Despite massive research efforts, the molecular etiology of bovine polledness and the developmental pathways involved in horn ontogenesis are still poorly understood. In a recent article, we provided evidence for the existence of at least two different alleles at the Polled locus and identified cand...
