DNA pedigreeing of wool and fat lamb breeds offers breeders the opportunity to boost productivity while cutting the costs of traditional breeding techniques. The productivity of Australia's wool sheep breeds, most notably the Merino, has not increased substantially in the past three decades. Researchers will also use the system to identify genes for rapid wool or meat growth and also to identify rams carrying genes for undesirable characteristics like coloured wool.
Coloured fibres reduce the value of a bale.
DNA is the chemical building block of genes.
