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.
Hybrid vigor is gone. Breed the F1 to a third unrelated breed and you would maximize heterosis(hybrid vigor).
If you are really sleepy read this it is a sure fire way to go to sleep
