Misteri New Blood type di pecahkan

[kullatiro]

ScienceDaily (Feb. 23, 2012) — You
probably know your blood type: A, B,
AB or O. You may even know if you're
Rhesus positive or negative. But how
about the Langereis blood type? Or
the Junior blood type? Positive or
negative? Most people have never
even heard of these.

...

 Beyond the ABO blood type and the
Rhesus (Rh) blood type, the
International Blood Transfusion
Society recognizes twenty-eight
additional blood types with names like
Duffy, Kidd, Diego and Lutheran. But
Langereis and Junior have not been
on this list. Although the antigens for
the Junior and Langereis (or Lan)
blood types were identified decades
ago in pregnant women having
difficulties carrying babies with
incompatible blood types, the genetic
basis of these antigens has been
unknown until now.
