[Jacob-list] "lilac carriers"

[Dan Carpenter]

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?
