The question remains why Rh negative blood has remained at a low percentage within the European population over thousands of years. As previously discussed on this blog, there are many factors playing a role in keeping percentages down.One, the main one possibly, is of course the fact that pregnancy incompatibility has over the centuries kept Rh negative women from being able to pass on their D negative status as freely as mathematical conclusions would permit them to. The example in the image is excellent using self-pollination to show a 3:1 ratio in the F2 generation.
