Jerusha lives with a person who's aunt was the owner of the Desert Caper herd a few generations back in Jerusha's pedigree. You will find the Desert Caper lines behind several Kastdemur animals.
Yesterday I received an E-mail back from the owner of Diva's littermate sister. Jerusha's test results were back in, Jerusha is a carrier. While I am less than thrilled that she is a Carrier, I am very grateful she is not Affected.
What this means for this observation: The few pictures we have of Diva and Jerusha together give us a comparison of a litter mate of known status. One Affected, one Carrier.
