[Jacob-list] "lilac carriers"

[Dan Carpenter]

You're right, I left a word out.  A "regular" or "true" lilac should ALWAYS
produce carriers OR more true lilacs.   I meant to say If both parents are
"regular lilac" carriers.the non-lilac offspring have a 67% chance of being
carriers (as you say).  If both parents are true lilac, then the lambs
should be true lilac.  It's the other non-black colors being lumped in as
lilacs that mess up these percentages

If "true" lilacs are a recessive, as I think you agreed, then wouldn't the
offspring of a true lilac carry one lilac gene from that parent and thus be
a carrier?  The non-lilac offspring of two proven lilac carriers would have
a 67% chance of being a carrier, but it looks to me that the offspring of a
true lilac bred to not-lilac is going to carry lilac. 
I am calling "true" lilacs those lilac sheep that bred together, always
produce lilacs. I have heard the term 'dark lilac' to refer to those lilacs
that do not breed true. I use the term 'chocolate lilac' to refer to sheep
with chocolate facial and leg markings and wool. Mine breed true. I see very
few 'blue' lilacs around here.

Some people say you can tell by the presence of an "eye ring," but I haven't
found that to be reliable.  If both parents are "regular lilac" (as opposed
to, say, "chocolate lilac") the non-lilac offspring have a 67% chance of
being carriers.  If one parent is regular lilac the non-lilac offspring have
a 50% chance of being carriers.  If one or both of the parents are called
lilac, but are not regular lilac, then it's anybodies guess.

Hi, all-

 

I see sheep advertised from time to time as lilac carriers. Can we know if a
non-lilac sheep is a carrier before seeing lilac offspring? If both parents
are lilacs, would a non-lilac lamb have to be a carrier? I am thinking of
simple genetics where I'd expect some would be non-lilac and not carriers,
some non-lilac but carriers, and some lilacs if both parents were lilac. If
only one parent was a lilac I would expect a significant percentage of
non-lilacs to NOT be carriers. But nothing is simple with Jacob genetics, is
it?
