As in the past information tricked in, I sporadically made posts about Rh negative frequencies as information came in. Since then I have put up the first chart of blood type frequencies worldwide that has been turned into graphics by others.
However:
We still lack significant confirmation on some claims, so I would like to now take the opportunity to highlight blood type frequencies focused on Rh factor alone.
These maps were published years ago based on my findings.
In other words: This post contains updates.
Poland has been found to lead on a national level, mostly due to high frequency in the region of Lower Silesia.
