I juat called up redhead HQ and I am now getting word that none of them, absolutely NO REDHEADS, are intersex. Many are saying this is because they already have enough mutations as it is and aren’t allowed to stack any more.
So, for the full answer, zero.
As for the second part, i was recently looking this up and wikipedia has a nice table displaying blood group occurence by country. We’re going to model the population of all redheads globally as scotland and ireland because that’s simply the very closest our scientists can get!
For ireland, 5,233,461x0.03=157,003.83 For Scotland, 5,546,900x0.03=166,407
As you can see, ireland’s occurance of ab blood isn’t even a whole number! This ks because many irish people have hybrid bloodstreams; part-whisky, part-haemoglobin.
this was too interesting a question not to look at more seriously
If I understand correctly it’s like:
-
8,279,825,750×0.03×0.015×0.017 = 63,340.6669875
-
world pop x AB incidence x redhead incidence globally x intersex traits (any) incidence
-
And using only “noticeable”/ significant intersex traits, only 0.018-0.05 percent of the world seem to display these. So
-
8,279,825,750×0.03×0.015×0.00018 = 670.66588575 ≈ 671.
-
But maybe intersex varies depending what genetic group you belong to or where you are born? AB blood certainly does - in the afforementioned Ireland and Scotland it’s roughly the same as global AB incidence, 3% of population, but it is most common in Korea. I believe no ethnic koreans are red headed so this ahould bring the numbers down significantly.
