[Jacob-list] White lambs

The genetic explanation I have heard for white Jacobs is in line with
Juliet's explanation: The lamb expresses one large spot. Presumably the
white Jacob would produce spotted lambs.

His sire is Kenleigh's Frankie and dam is Rollings Hills Elsie.
He sired 6 lambs this year.
If interested, please let me know and I will email photos.

Lambing just started for me, and with a surprise, a Totally white ewe.
No non-Jacobs on the farm since I started with Jacobs, or with
neighbors. Has anyone else had this happen before?

Not for a long time, but during our first couple of years with the Jacobs,
we did have a set of triplets with two of the three all white (with blue
eyes). Pre-registry, so it was hard to track where it came from, but Ingrid
Painter does mention this happening in her book on Jacobs, and provides a
couple of possible genetic explanations. Ours wound up in our mixed
(commercial) flock, and their lambs looked like any other Jacob crosses -
mostly dark with badger markings.

Over the years, people have posted on this list about white lambs from
Jacob parents. It seems it does occur. If you search the archives, you
can find reference to white lambs.

Since it's almost impossible to eliminate recessive alleles from a
population (witness red in Holsteins), it's highly likely that there are a
few Jacobs out there that carry the genes necessary for white...and it
doesn't have to indicate crossbreeding. I'd love to take a look at the
pedigrees of the parents!

I have never had a totally white lamb -- however, this year I have had two
nearly all black lambs......never had that before.
We have a small flock.....only had six ewes who were bred this
Spring.......so we have 12 lambs..........and 10 are rams.

As a Jacob is genetically a black sheep with white spots, would a totally
white one not simply be expressing an all-encompassing white spot? Or is
that too simplistic?
