Looks like a spotted gulmoget to me, which would mean either another ram snuck in a breeding or one of the parents is extension dominant!
ReplyDeleteHi Michelle,
ReplyDeleteThank you for your input. I am still at a loss trying to figure out all the genetics, then patterns and markings.
This ewe has come from solid colored stock. The ram came from Jim Chastain in Oregon, there again I'm not certain on his background for markings or patterns.
Two solid sheep can only produce a pattern other than solid (katmoget, gulmoget, Ag or white) if one or both of them carry the Extension-dominant gene, which LOOKS like the recessive Aa (solid black or moorit) gene but acts as a mask over whatever genes are at the A locus (which is why it is frowned upon by most). I know there are a few Extension-dominant Shetlands in North America, but you also have a gulmoget ram. Is there ANY chance he could be the sire?
DeleteWe did not have any escapes when we set up the breeding groups. I am expecting more lambs from this black ram used on other ewes. Is there anything, any way to verify a possible extension-dominant gene with this ram. By the ewes that are bred to him and the offspring that are born?
DeleteI looked up your ram's pedigree and it didn't look like he has ANY gulmoget in his ancestry. If he doesn't carry gulmoget, then the extension gene can't be covering it. That would lead me to suspect the ewe. Couldn't look up her pedigree because she's not listed in your ewe page, though.
DeleteYes, I need to get my ewe page updated. You know I was suspicious when my first crossbred ewe had a gulmoget lamb and I had bred ALL my white crossbred ewes back to their sire for the meat market and the first one to deliver had a gulmoget lamb, I thought that the lamb should have been white.
DeleteI still don't know how Bargs could have gotten to those ewes. I moved those ewes from a separate location, directly in with the ram I chose to breed them to.
Checked on DNA testing, kinda pricey.
....chastity belts for those rams!
Someone mentioned a much more reasonable test done with wool samples (I think); I'll see if I kept that info somewhere....
