Both sexes are always horned, and the rams tend to have larger and more impressive horns. All the solid-coloured animals belonged to Laban. Then, in God’s providence, the flock would give birth to spotted animals. They can secure adequate nutrition with minimal to no supplementation, even in the presence of suboptimal soil conditions. The face should have a white blaze extending from the poll to the muzzle.

We simply don’t have enough details. But one section of this account has caused much confusion and speculation. A FREE downloadable study guide is available from creation.com/tga.  British Jacobs most often have two horns, while American Jacobs are more often polycerate. The Hebrew literally says, "it shall be [i.e., in the future] my wages." As a result, the American Jacob has retained nearly all of the original phenotypic characteristics of its Old World ancestors while its British counterpart has lost many of its unimproved physical characteristics through cross-breeding and selective breeding. Laban thought he would reap a great profit by receiving from Jacob the great majority of the flock. The ability to switch genes on and off, even across generations, only increases the potential complexity of any explanation of what happened among the flocks living on the hills of Paddan Aram about 4,000 years ago. 'Jacob sheep' from the Bible return to the Holy Land after red tape shorn away. Ideally, horns are smooth and balanced, strongly attached to the skull, and grow in a way that does not impede the animal's sight or grazing abilities.  The skin beneath the white fleece is pink, while skin beneath coloured spots is darkly pigmented. Laban cheated Jacob again by taking off with the motley and darker coloured animals. Jacob kept the sheep separate from the goats and made them face in the direction of the streaked and black animals of Laban's flock.  The Jacob was introduced to Israel in 2016, when a small flock of about 120 head was shipped there from Canada by a couple who believes the breed is the same one mentioned in Genesis. Worse, since the Bible does not to give us a detailed description of the pedigree of Jacob’s flocks, it is difficult to deduce exactly what transpired. We call these alleles. However, without access to Jacob’s animals, we cannot say anything for certain. S/s, R/r, W/w, etc. The Jacob is a small, multi-horned, piebald sheep that resembles a goat in its conformation. The X chromosome is a ‘sex chromosome’, which is different than all the other chromosomes.  The discovery offers hope of a possible pathway to effective treatment in humans. Barbara Rischkowsky, D. Pilling (eds.) Interestingly, one research group found that there are multiple differences among three coat colour variants in goats.6 It is possible that there are three different versions (alleles) of the same gene, or there could be three separate genetic pathways involved.
