The allele for black coat colour is dominant relative to the allele for lilac in Jacob sheep and is affected by a single gene locus. The percentage of this colouration, as opposed to white fleece, across the body has a heritability value of 0.255. The mode of inheritance for horn number in these animals is less clear, with neither the trait for 2 horns, nor for 4 horns being totally dominant, based on crosses of 2 x 2-horned parents and 4 x 4-horned parents; although in these examples the majority of lambs had the same number of horns as their parents. However, when one parent had 2 horns and the other had 4 horns, the gender of the 4-horned parent appeared to influence the frequency of 4-horned offspring; 77% of lambs born to a 4-horned dam being 4-horned, but only 50% when the 4-horned parent was the sire. These data suggest evidence for sex-limiting factors being involved in determining the number of horns in this breed.
