For instance, the RBPMS2 gene, found in YAK is related to age at first calving in Romosinuano and Costeño-con-Cuernos cattle breeds (Fernández et al., 2019) and the gene ATG16L2 found in MG cattle is related to mastitis recovery in Danish HOL cows (Welderufael et al., 2017). This evidence concerns the gene RBPMS2 and mastitis.
