Researched "English Blue" of the BFL

I found a good explanation of English blue in an article on Gotland sheep, English blue is co-dominate with katmoget, gulmoget, and gray agouti gene. The parents each contribute a gene for color and a gene for pattern so the possibilities are endless.
My neighbor starts lambing in May.......if there is a promising polled Icelandic ram lamb will get him .I will find a stocky well built ram and then look at the color. Every color and pattern will be available, as she has 50 ewes lambing  bred to White, Black and a Spotted ram, Alot of the ewes having the agouti gene so have "pastel" coloring

Til later

Jerry did you not get my email stating all of this to you?

Remember all English Blue BFLs are homozygous for it Aeb/Aeb. They can only produce Aeb lambs (and black at that, as there are no moorits in longwools). They can be Aeb/Ag, Aeb/At, Aeb/Ab (English Blue/Ag, Engligh Blue/Katmoget, English Blue/Gulmoget, but you won't just get the shetland marking alone, as no BFLs to date have the Aa allele.

I had two more mules born this morning from Flopsy. Both boys, Both English Blue (and carry Aa and moorit from their mom)

Hi Jerry,
I don't know about the Icelandics and their color genetics. But I can speak from 15 years of experience with the Bluefaced Leicester's and their natural color (black in the UK) version. Funny the Brit's don't call it 'english blue' that is a term coined by the Australian's.
My purebred flock of Bluefaced Leicesters, will normally produce 25% colored without trying.
Unlike some other USA flocks, mine do not have crossbred genetics of Wensleydale, Romney, Romanov, etc.. added. Just 'traditional' Bluefaced Leicester. When I put a colored to a colored it always equals 100% colored lambs. This is out of over 100 natural colored BFL's born here at Beechtree. I do however see shades in the natural colored, from silver saddles, to pewter, to a very dark charcoal. Also, they don't fade to light silver or washed out whites, even in the 7+ year old Colored BFL's. Now when you start throwing in different breeds and all their color patterns, then it is a whole different ballgame.
