A very useful summary was provided by Gehrke et al. (2020): "With respect to scurs, the most commonly accepted model of inheritance was initially proposed by White and Ibsen [(1936)] . . . and revised by later studies [Long and Gregory, 1978; Brem et al., 1982] . . . . The model assumes that four biallelic loci interact to control the development of horns: the “symbolic” horn locus (H, which is suggested to be always present and homozygous), the polled locus (with alleles P for polled and p for horns), the scurs locus (Sc for scurs and sc for no scurs) and the African horn locus (Ha for African horns and ha for no African horns) [White and Ibsen, 1936; Long and Gregory, 1978] . . . . Scurs are expected to be masked in otherwise horned animals (p/p), but there is discussion about an epistatic interaction between the polled and scurs loci. However, in the literature contradictory results are reported on the mapping and expression of scurs, and some studies discuss whether the development of scurs depends on sex, the genotype at the polled locus, and heterogeneity at the scurs locus [Capitan et al., 2009; Brenneman et al., 1996; Long and Gregory, 1978; Tetens et al., 2015; Wiedemar et al., 2014] . . .
