[QUOTE="Anonymous, post: 13320"] I am going to weigh in on this subject with my understanding of the subject, but take what I say with a grain of salt as I am an Ag Engineer and not a geneticis. The F-1 designation identifies an offspring as a first generation cross of two genetically different breeds. Its importance to the cattle industry comes from the fact that a normal F-1 cross resulting from two purebred parents will exhibit the maximum amount of hybred vigor which usually results in increased rate of gain, increased fertility, etc. If one or both of the parents are a crossbred, then while you still technically have a crossbred offspring, it will have a reduced amount of hybred vigor and will not be an F-1 unless a third/fourth breed was introduced without any or the original 2 breeds being reintroduced. (ie. angusXherford animal bred to a charolais or charolaisX(non-angus or herford) that didn't have any angus or herford breeding would technically still be an F-1) Sorry about the length and if I am wrong please correct me.
