Jacinto et al. (2022) reported that "Whole genome sequencing (WGS) was performed using genomic DNA obtained from ear tissue from the [affected] calf. . . . Variant filtering did not reveal any private homozygous protein-changing variants present in the genome of the affected calf, making a possible recessive inheritance unlikely. Assuming that a spontaneous mutation affecting a protein-coding gene is the cause, filtering for private heterozygo...

The absence of horns (polledness) is of substantial benefit in cattle, from an economic and welfare point of view: bruising due to horns is eliminated, and the stress associated with de-horning is avoided. (Information complied by Ulrika Tjälldén and Vanja Kinch, Uppsala, March 1998). In addition to naturally occurring variants for this trait, variants have been created artificially: Genetically-modifed organism; GMO.
