No, the imprinting stat bonus is not passed on. When a baby is hatched (with 0% imprinting) or a wild dino is tamed, whatever their stats are, those are the ones that can possibly be passed to the next generation.
Not all max level dinos are worth taming, unfortunately, it is not possible to know that before you tame them. As Grem said, you a pair or more of dinos and start breeding them. And yes, if you really want a monster uber dino, you will do extensive inbreeding.
As I’ve mentioned, I keep a spreadsheet of all the dino stats I am breeding. For each stat, I find the max stat out of the entire herd and highlight it in the spreadsheet. Then when I breed, I find all the possible combinations that could give me a baby with all the highest stats. If the highest stats are spread across more than two dinos, I breed some of them until I get a baby that has highest stats, then add the baby back into the breeding herd.
Also, you need to be an opportunistic tamer. As you travel around, whip out the spyglass and check out the levels of random dinos. If you have the time and energy, tame anything that is even moderately high level. Occasionally you will find a lower level dino that is min/maxed, i.e. one stat is pumped really high while the rest are really low. I’ve tamed non-max level (130/135 stuff with max 150) that had a useful stat.
If you find one that has a better stat that you want, you add it into your breeding herd. Or if you get a mutation in a stat you want. It will take time though, but once you get a male dino with all the max stats you want, you’re almost there. Now you just use that male and breed him with all your females. Eventually the RNG will smile on you and you will get several max stat females.
Once you have a max stat male and 3 to 5 females, you can go have fun with the rest of your herd. I generally take them out and fight a giga or titan. If they win, I find another one, and another, until they lose. Why? Because at that point you could easily have a herd of 30+ dinos. Don’t be afraid to cull the herd when you get a breeder dino you no longer need.
Those are my ramblings on how I handle breeding. I’ve feed so many of dino babies with the meat from another dino baby that didn’t quite measure up. Another person I played used the same process as I did. We started calling each other Dr. Moreau for all the dinos we killed that just didn’t quite meet expectations.
