[QUOTE="Anonymous, post: 4935"] An exerpt from the attached article: Retaining heterosis The maximum heterosis that can be attained for any crossbreeding system comes from mating two unrelated breeds, for example mating Charolais and Angus. We refer to a first cross animal as the F1. If we mate two F1 animals together to form the F2 we find that half of the F1 heterosis is lost. Barring inbreeding effects this half of heterosis remains in the F2 and also in the F3 and subsequent generations. <A HREF="http://chuck.agsci.colostate.edu/~pcharter/journ/com.html" TARGET="_blank">http://chuck.agsci.colostate.edu/~pcharter/journ/com.html</A> dun [/QUOTE]
