Technically, the Tukidale is a not a new breed of sheep, but rather a Romney sheep carrying the T gene for hair. The breed originated on M.W. Coop's property in New Zealand from a ram born November 26, 1966. The ram possesed the T gene, which is dominant. The T gene is responsible not only for producing the specialty carpet-type fleece, but also the formation of horns in the in the male and, to a lesser extent in females.
