Why is sheep wool white?
If a sheep inherits the gene for white pattern from either or both parents, it will be white. That is because the white gene is “dominant” over all the other genes at the Agouti locus.
Why is wool white?
Most sheep used for fiber have white wool. The main reason is that white wool can be dyed to almost any color. It probably is a trait from human breeding.
Is wool naturally white?
White wool is the generic term for any wool that is in its natural un-dyed state. This ‘pure’ wool is more valuable than off-white wool as this may contain dark hairs which cannot be dyed, and therefore cause imperfections in the fabric.
What did sheep do about their wool before humans?
A common question regarding shearing is “what happened to sheep before people sheared them?” Before electric motor shearing machines there were hand shears, which some people still use today. Before hand shears, ancient people would pull the wool that naturally came off the sheep, or “roux” the wool from the sheep.
Why are sheep mostly white?
In sheep, a white fleece is the result of a dominant gene that actively switches colour production off – that is why most sheep are white. This is quite a rare occurrence though, and in most white sheep breeds only a few white sheep are heterozygous for black, so black lambs are usually much rarer than this.
Why are sheep colored?
Why do sheep have patches of color painted on their wool? Farmers “paint” their sheep for identification. When mating, the ram mounts the ewe and a bit of dye is deposited on the ewe’s upper back. This way, the farmer knows which ewes have been impregnated and moves them on to another field away from the ram.

Breed Association Website: ncwga.org/ Natural colored (non-white) fleece colors appear in many breeds of sheep, although over millennia, in many breeds, sheep with colored wool have been selected against, as the goal was to produce uniform white fleeces for commercial …
Why don’t sheep have different colors?
There are thousands of years of breeding color out of sheep behind us, leaving only ‘primitive’ breeds like Shetland and Icelandic routinely expressing color in their wool. And research on sheep color genetics is slow because most ewes produce one or two lambs a year, not the several dozen kits a rabbit doe can produce.
Why is white wool more valuable than colored wool?
Color In the commercial market, white wool is more valuable than colored wool because it can be dyed any color. Even the wool from sheep with white faces is more valuable than the wool from sheep with dark or moddled faces because the fleeces from non-white face sheep may contain colored wool or hairs which cannot be dyed.
Why is the wool of some sheep more valuable than others?
Even the wool from sheep with white faces is more valuable than the wool from sheep with dark or moddled faces because the fleeces from non-white face sheep may contain colored wool or hairs which cannot be dyed. In contrast, naturally colored wools are often favored in the niche markets. Wool marketing In the United States,…
When did your interest in sheep color genetics start?
My interest in sheep color genetics started when our first lambs hit the ground in 1999. We bred our ewes to a moorit (brown–see color terms for definitions of color genetics terms as I use them.) ram and had six moorit lambs, apparently.
