Thanks for the reply.
This is my first year with my first hive so worrying about inbreeding in my apiary is somewhat premature I guess.
I have Carnie/Italian mutts at the moment and my plan is to focus on Old World Carnie's, Caucasians, Russians, German derived stock if I ever find some, and certainly any swarms I can get my hands on. All of them supposedly will be more adaptable to my local conditions ie rapid fluctuations, with frequent cold and wet spells throughout the year. With this many subspecies and their resultant mutts I guess I won't have to worry about inbreeding and a reduction in genetic diversity for the first few years anyways.
Hope the rest of you guys are warmer than I am
