Wao, didn't know your wife is Also on hive ☺️, amazing...
That's very true, diversity also socialization have made it so. Though the incidence of people with the hh is very low.
Regarding the question of possibility of additional antigens playing a role, so far, none to my best of understanding. The ones I discussed here are the major ones. Unless if we decide to delve into the world of Major Histocompatibility complex MHC molecules - antigens that
are looked out for when it comes transplantation of (solid tissues).
I had to put that in bracket because blood is also a tissue but I'm liquid form.
MHC sure will be a topic for some day.
Tanks so much for the lovely contribution ❤️💕
My wife used to be quite active in the past, but has not really any time for it at the moment.
That may possibly be too involved for a layman like me ;)
Lol...maybe
