Reply To: DNA testing and Halchah

Sam2: WADR, blood typing is not DNA analysis. And how about cases that would not create Mamzerus, for example Yerusha? Agunah (as you point out)? I don’t think anyone would claim that in this day and age it would create a Mamzer Vadai. However, there is that din of Yakir that could pop up. Even if we may say in 50 years that the testing is not accurate, wouldn’t it create a “Tzarich Heker”?

akuperma: Yes.

I think #3 may be relevant to prove Yerusha, especially if there are no other known heirs. If #2 is not accepted, I don’t understand why #1 would be. Especially if the “Rov” was known to be in doubt.
