My education and interests being scientific, I studied inheritance and genetics - and one of the difficulties when breeding my colourful little budgerigars is that from any individual ancestor only half the genome is passed on to any offspring.
It is usually necessary to spend a long time trying to obtain a strain of individuals with one particular inherited feature, though I did have one cobalt blue bird (called Roger) who became the source of lots more cobalt blue offspring than statistically probable.
With people and tribes, I pity those trying to make the rules, because it would be quite possible for someone with only a limited amount of tribe DNA to appear 'full blooded' if they inherited the genes for tribal appearance, but for someone with - for instance, one great grandparent being an incomer, to resemble their great great grandmother or father.
