The poll microsatellite DNA marker test has been used for poll testing Australia’s beef industry since 2011, and largely relied on the submission of phenotypes (horned, polled, and scurred) as a reference dataset to estimate genotypes with an associated probability. Recently poll SNP based testing has become available, which does not require phenotype submission and provides a more conclusive genotype result. The following summarises changes to poll DNA testing, how tests differ and potential changes in genotype results. |
