[QUOTE="jnowack, post: 223241, member: 3954"] Yes the polled (P) and horned gene (p) are a different gene pair than the scur and non-scur genes. But the scur gene theory says that scurs are dominant in bull and recessive in females. It also says that no scurred animal has ever been proven homozygous polled, which means that all scurred animals are heterozyous polled. So while the polled/horned locus is different from the scurred locus, the expression of scurs in dependent on the Pp genotype. [/QUOTE]
