Bloodlines=Y hg. Rothschilds are J. Cohens are J. Saudis are J. Friggin Bernie Sanders is J. CMH of Levites is J.
Sure Rh- might turn out to be important (iq/toxoplasmosis correlation) but i see bloodlines being more paternal lineages as rh+/- might flip whenever they feel like it
Ever done genealogy? I am too distant cousin of Obama and a direct descendant of most of royal houses of Europe but it doesn't mean anything. If you are european descent you will also have these connections. Pretty much everybody has these connections, and all those examples of GW Bush being 10th cousin of Trump are almost meaningless.
When looking for bloodlines, they have to meaningful. Being somebodys aunts 7th cousin means absolutely nothing.
