Can't sleep. Doing some late night reading and got on to some Leachman genetic talk. One thing leads to another and now I have questions that Google isn't answering the way I am looking for.
Let's just use simmental and angus as examples in this question.
Purebred angus mated to Purebred sim will create an f1 half blood. This mating creates hybrid vigor
Let's take 2 half blood f1 sim angus and mate them. The resulting offspring would be the same percentage as it's parents 50/50 but is this calf now a f2? And is the hybrid vigor gone?
Few answers I keep coming up with say the offspring of 2 f1s is an f2 but call it a 75/25% mix which the percentage part isn't correct.
When you take a breed and make it black, and then breed within the breed for some Angus characteristics, you end up with more Angus genes than you might think. Theoretically a (edited JHL is right did say f2) BC1 is 75/25 but in reality we don’t inherit equally from all of our grand parents, so it might be 70/30 or 80/20.
