Introduction
Sheep (Ovis aries) have been selectively bred to continuously produce single coated wool fleece rather than coats composed of an outer hair layer and an inner wool layer. True wool, as opposed to hair, is characterised by its high follicle density in the skin, small diameter, and high crimp (waviness) [1]
Genetic origin of Wool
The modern wool-producing domestic sheep differs from the ancestral sheep in that it has a single woolly coat and does not shed.[2]
