    • Abstract

       

      1. A brief description is given of the Piebald breed of sheep. While there is a considerable range of variation in the extent and nature of the spotting these sheep breed remarkably true for the piebald character.

      2. The-result of crosses with other breeds is the production of self-blacks.

      3. A back-cross of the F1 to white gave six whites and five blacks. A back-cross of the F1 to piebald gave sis piebalds and four blacks.

      4. Piebald sheep differ from other breeds in that they possess a dominant black factor and a recessive pattern factor which restricts the black to certain areas.
