3- I have witnessed many villages here that are the lineage of just one grandfather and the whole village comprises of population as a result of cousin marriages since generations upon generations throughout centuries. A few examples are Ldhay vala Virkan, Bhattianvala (where in fact due to cousin marriages, all men and women are exceptionally well-built, tall and strong). Jaliana where my friend resides and there are three villages comprised of the descendants of just one grandfather intermarrying each other and none of them has any defects, in fact they are also very strong, agile and famous for their fighting skills. And all these villages by no means have little population but as a result of cousin marriages throughout centuries, comprise of thousands of residents.
My maternal side of the family which is baloch almost always marries within cousins and I haven't seen any disorders when it comes to them, in fact, almost all are well-built, strong, sharpest of features and fairer just like kurds (their ancestors). All are exceptionally intelligent as well. Agile to the maximum.
In fact, the issue arises when certain families carry certain diseases and ailments which then get transferred from both sides due to being cousins in a marital relationship and the children become more likely candidates for carrying and exhibiting the characteristics of the disease. If they marry within other families, the chances reduce as other genome interferes with the fabric of the former and creates another pattern.
