For those whose bee genetics are a bit rusty or non-existent, I
recommend visiting
http://maarec.cas.psu.edu/bkCD/HBBiology/breeding_genetics.htm.
The basis of bee breeding is described there in simple and
understandable terms.

http://www.beeculture.com/beeculture/digital/2002/column40.htm offers an
article by by Tom Sanford that provides further links on the subject.
