A black-moorit mosaic-colored Icelandic ram.
A description is given of a black-moorit (black-chocolate brown) mosaic male lamb born in Iceland in the spring of 1982. A testmating resulted in 10 moorit and no black offspring from moorit dams. The results suggest that the mosaic color resulted from a mutation of the recessive allele b for moorit pigment to the dominant allele B for black pigment during fetal development, and that the mutation has not affected the gonadal tissue.
