Moreover, the ROH island shared by BP and Pi populations (6: 38,429,780–39,461,621) included genes like LAP3 (Leucine Aminopeptidase 3), which may greatly benefit the simultaneous improvement of mastitis resistance and milk yield traits in dairy cattle [52], and MED28 (Mediator Complex Subunit 28), a gene involved in the regulation of cell proliferation and cycle [53]. The gene discussed is LAP3; the disease is mastitis.
