Breeding any type of animals is really complicated and you can get throw backs from generations behind the parents. Even breeding with domesticated animals where you know the pedigrees back several generations it is still a challenge to get what you want.

IMO that type of breeding in wild deer is all but impossible. The best thing you can do is try to keep buck/doe ratios and numbers correct, and let the Bucks get some age on them.

That's one thing Trophy deer have in common. They have a little age on them
