The question really is, does your tribe identify you, or do you identify your tribe? if it be the latter, than you can indeed transcend your tribe. Memetics is the way you identify your tribe. Identify the memes in your life, and put them into baskets. The biggest basket is perhaps the tribe to which you are most affiliated.
This indicates that you DO NOT necessarily inherit your parents tribe automatically, through bloodlines, DNA etc, but rather you identify the memes which you follow, understand, interprete, perpetuate, and from this you can understand the question that started this monologue.
An even BETTER analysis? is list tribes you BELEIVE you belong to. Ask an individual from this tribe to do the above and see if your meme baskets match. You may be surprised to realize your true identity. And as I’ve said before:
Identify your tribe correctly. Aim to not need to have one.
