something to do with Rh Negative blood type?
>http://www.rhesusnegative.net/staynegative/popular-questions/are-rh-negative-people-more-likely-to-have-red-hair-andor-freckles/
Looking at the pictures of members on People with Rhesus Negative Bloodtype, it becomes very clear that out of 1,000s of members, more than half display signs of red hair and/or freckles.
But how exactly does that correlate with rh negative blood?
Just like the rh negative gene, the red hair gene (MC1R) is recessive.
1 in 4 people from the general population carries this red hair gene.
That means out of 2 random people coming together, their chance of having a red haired child is 1 in 64.
While within the general population the chances are 1 in 4 that you carry the MC1R gene, 85% of people with freckles carry it.
