Background on the Genetic Tests
Background information on the two main genetic tests behind this registry.
Increasing prolificacy in sheep by selecting the desired genotypes at the FecB (Booroola) locus
The Booroola gene (FecB) affects litter size. One copy raises prolificacy; two copies raise it a little further, at some cost to lamb survival and growth rate. Further articles and links will be added here.
Increasing sheep resistance to scrapie disease by selecting the desired genotypes at the PRNP locus
The PRNP gene determines an animal's resistance to scrapie. Results are graded from NSP group 1, the most resistant, to NSP 5. Further articles and links will be added here.
