[QUOTE="Ky hills, post: 1831046, member: 24816"] Around 20 years ago I had sheep. At that time they were breeding for sheep that were genetically resistant to scrapie. I don't understand or remember it well enough to hardly describe, but there was a gene that determines susceptibility to scrapie if the sheep is QQ then it's susceptible. QR would be resistant but could pass on the susceptible gene. The desired gene was RR which I reckon would be homozygous and I bought RR rams. Also if I remember right some breeds were more prone to scrapie than others but I don’t know which ones. My Suffolks never came back as QQ but just a small sampling. [/QUOTE]
