I am supposed to be going bald and grey at over 55 based on my genealogy but that isn't happening. I am in the 25% square. I have brown hair growing without grey and must get haircuts when it looks bad and shave every day. My cousin went bald at 45. I guess I rolled an 11 on the dice roll:)
I played with those things like other people do crossword puzzles. Some of them were so complex I drove my prof nuts. Not a perfect predictor, but darned close.
Depends on the gene — blood types A and B are codominant; type O means the genes that code for either A or B blood proteins are not present, so there is no blood type per se. 40 percent of the world (but see next paragraph) is A, 40 percent O, 15 percent B, and 5 percent AB (this last one due to having one parent who passed down A, the other parent passed down B).
There’s also the M and N blood group, which is terribly rare, and for the most part (for now) geographically restricted to the area around the Bay of Bengal I think, maybe an artifact of blam’s Sundaland refugees. ;’)
For that matter, I’ve heard of something called Bombay Syndrome; the conventional blood test returns a result of A bloodtype, but the genes are just a hair different, and an A transfusion will kill the Bombay blood patient.
