Re: [Alpacasite] Re: Detecting Genetic Collagen Ear Defect

jeff,

Thanks for the clarification. I believe this has been discussed on our
list before. Unfortunately I am a poor researcher and the archives seem
rather difficult to search. I seem to recall that something like this
has occured in a line of huacayas originating somewhere in the
NE(nothing disparaging against huacaya but it is what I recall).
Hopefully someone might contact you privately as many are ruluctant to
share that type of information publically. If I am incorrect and the
discussion was about a line of suri, I apologize ahead of time.

Good luck on your population.
