they are useful for research in population genetics.
they are useful for research in anthropology.

Explanation:

Blood groups other than ABO and Rh (such as MN, Duffy, Kell, Kidd, and Lewis groups) are not frequent causes of transfusion reactions. Transfusion reactions are more commonly associated with ABO incompatibility. These blood groups are useful in population genetics (as they show genetic variation in populations), in anthropology (to study human populations and their migrations), and in legal cases (like paternity - as they have a genetic basis).

Answer:

They frequently cause transfusion reactions.
