Colour inheritance in sheep. II. The piebald pattern of the piebald breed

  • J. A. Fraser Roberts


  1. 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. 2.

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

  3. 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. 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.
