Question:

Anyone have a thing for any particular blood-line?

Best Answer - Chosen by Asker: I am an A, Rh negative female, so I would prefer my partner to be Rh negative as well in order to have less difficulties during pregnancy.
Any other blood lines which are very small (kings use to marry between cousins, sisters...same happened in Egypt ages ago), may carry with them too many unwanted mutations, and wouldnt be good "candidates" for procreations. But then again, fresh blood may dampen the effects, and in this time the chances of finding such small groups of ppl are very unlikely.
