A note on differences in coat structure between the black and white areas of piebald lambs

Summary Data are reported on a phenomenon in which piebald lambs having a coat of intermediate hairiness have black wool which is not only longer and coarser than the white wool on the same animal, but which has a different coat structure in terms of the fibre type array. Possible explanations for this effect which is apparently caused by the gene that restricts the production of pigment to certain areas of the skin are discussed. Hairy lambs and woolly lambs did not have this coat difference between the two colours.
