Yes, I think that the range of intensity of colour in both the regular
colours and the modified ones may be caused by the interaction of other
genes. And, my experience is that intensity of colour also interacts with
pattern as we have been discussing.
Maggie has elaborated on how she has seen AebAa vary. I have certainly seen
that too.
Also, in Ag greys. I have some that are very light but some that are much
darker grey with many more dark fibres, even though both are AgAa.

... Hi Linda, and so a very " strong" self black with an Aeb might produce a black lamb which in other breeding combinations may prove to be "dominant black"?...
Hi Renee: I think dominant black is quite a different thing than what Maggie has termed strong self, at least the way I understand it. I think with strong self...
Hi Linda, ... there would be no change at agouti. It would still be AaAa, your strong self black AaAa has an additional modifier ( lets call it that for the...
Hi Renee: Maybe I was confused about your previous email. I thought you were equating strong self to Extension D. I agree, it seems possible that there is a...
Hi Linda, ... were equating ... No I'm equating "strong" to be an incremental modifier it would only become dominant if it obscured (was dominant to ) an...
Hi Linda, for now lets just use the terms modifier for a strong ( intense) modifier and dominant to refer to obscuring an agouti pattern. To take your Aeb...
Linda, Do you think that some of the English Blue that are dark and have small tears are heterozygous, while the ones that have large tears and saddle, ...
Hi Laurelen: I have assumed that the tears are an integral part of the pattern. Not sure about the ear rims, etc. and moustache as the "minimal" ewe does not...
Dear Linda, I agree all you have stated. White tears ARE definitive of the english blue pattern. Rimmed ears, moustache etc. are, many times, the first things...
Hi Maggie: No problem with the length of the response. I appreciate the time you take to state things clearly. Yes, the minimal ewe is AebAa out of what I...
The term "strong self" is just my own verbal expression of color experience at my farm. It seems that, for any given agouti pattern, family lines will have...
Thank you, Linda. You are correct. The agouti genes and the extension genes are quite different. And they exist on 2 separate chromosomes, to boot! I...
