The Polled trait is a genetic feature that suppresses horn development, resulting in hornless livestock which therefore do not require dehorning or disbudding. In cattle, several different dominant mutations to the locus known as POLLED are known to cause the trait. This test package analyses for two different Polled mutations: the “Celtic” mutation (Pc) and the “Friesian” mutation (Pf).


Chromosome: 1


Mode of Inheritance: Autosomal Dominant
