Hair diameter distribution was studied in wild sheep species (argali—Ovis ammon, mouflon—O. Musimon; domestic sheep—O. aries) and their hybrids. In wild species and their hybrids, rather distinctly separated subpopulations of thin (underwool) hairs (10–22 μm diameter) and thick (kemp) hairs (85–302 μm) were detected, and intermediate diameters were rare. In domestic sheep, the kemp subpopulation was very poor, not distinctly separated from the underwool, while maximal hair diameter was <150 μm. In wild × domestic crosses, the kemp subpopulation was clearly expressed, shifted to lower diameter range, and maximal diameters was <200 μm. The same restriction was found in two-month-old wild species lambs compared with adults.
