Strangely blood testing is more pf problem than DNA testing because of
the gemara that various properties of the child come from each parent. Thus,
if the blood comes from the mother it cannot be used to establish paternity.
Since this has no basis in modern medicine some poskim like R. Herszog
disregarded the gemara (ie it is philosophic and not halacha le-maaseh).
Others like the Tzitz Eliezer imply we accept the gemara against modern science.
DNA is better since there are no gemaras that deny its validity.
hence. the question
is "just" the more general one of when do we accept science evidence
as a substitute
for testimony
