I took a class on it, there's a reason you can dedicate a class to it, it can be a lot more complicated then you think. In one of my dairy classes we looked at a chart of expressed traits, what % is genetic vs environmental. For example, feet and legs are 70% environment and 30% genetic. There's a lot to learn, but it's interesting. One of the big take home messages is that the more traits you try to breed for, the slower your genetic process will be. The fewer traits you want to improve and focus on, the faster your progress will be.

That's an interesting idea....... Well, I guess I'll find out when I go to college for beef genetics!
The eternal optimist...you will be well suited for ranching! :wink: :) If you truly benefit from college, you will leave with more questions than you came with.

Homozygosis produces consistency. Homozygosis comes from concentrating genetic by closed herd linebreeding...just as was done to develop every breed of cattle.

Crossbreeding/out-crossing gives us heterosis and heterozygous genetics which leads to inconsistency. That's why replicating Oldtimer's heifer is like a cat chasing its tail.

Phenotype is a result of the interaction between genetics, endocrine system, and environment. The more heterozygous the genetics, the more variable the endocrine system and the more effect the environment will have on the final phenotype.

Crossbreeding/out-crossing should be the domain of the commercial cattleman.

Purebred/seedstock producers should be closed herd linebreeders.
