Some areas have a strong familial tree. Even with new blood over 100+ years, some genes may be dominant. I wonder if it's that, plus the environmental factor.

I wonder if it's that, plus the environmental factor. A mutated gene, dominant, always passed on, making the population susceptible.
- _yb2s 2y agoThat is not how a dominant trait in genetics works- it means you only need one copy to express the phenotype, but it is no more likely to be passed on than any other genetic trait. It is possible to have a trait that occurs with high frequency in a population- so that almost everyone has 2 copies of it.
