Cross-species summary: Horns are paired appendages with a bony core that is attached to the skull and a keratin outer sheath. There is substantial variation in the extent of horn growth, making classification difficult. However, in general, the presence or absence of horns can be attributed to the action of two alleles at an autosomal locus. The type of gene action varies considerably between and among species. Absence of horns is called 'polled'. See also entries for 'scurs'.

Molecular basis: By whole-genome sequencing with an Oxford Nanopore Technology's minION sequencer "four homozygous poll (PcPc), four homozygous horned (pp) and three heterozygous (Pcp) Brahmans" and comparing the sequence in the polled region, Lamb et al. (2020) confirmed that the polled allele in the Brahman breed is the Celtic allele. See 'OMIA 000483-9913 : Polled/Horns in Bos taurus' information on the variant.
