Kosher speciation Generally speaking, we have a rule that "kol hayotzei min hatahor tahor, vichol hayotzei min hatamei tamei" ("that which comes from a kosher species is kosher, and that which comes from a non-kosher species is non-kosher"; see Bekhoroth 1:2). Since this new species comes from kosher and non-kosher species, there would be several potential ...

I'd asked Rabbi Hershel Welcher of Queens a similar question, about goats that were given a bit of spider genes so they would produce gossamer in their milk. He felt the concept of "zeh v'zeh gorem, mutar" applied -- as the spider genes would not have sufficed to produce an organism, such a goat is kosher. So the same should apply here.

The Chasam Sofer (Toras Moshe parshas Shemini) writes that the meaning of the Medrash (cited by many Rishonim) that the pig is called a חזיר because עתיד הקב"ה להחזירה לישראל - Hashem is going to "return" it to the Jewish people - is that the physiology of the pig will be altered to chew its cud (the Kosher sign that it currently does not have) and will ...

myJewishlearning adresses the question and states this is unequivocally permitted There is no halakhic problem with pigskin and pig heart valves. Beyond that, there’s a very important tenet of Judaism called pikuah nefesh, or, saving a life. According to Jewish law, any of the mitzvot in the Torah (except idolatry, murder, and forbidden sexual ...

This question is relevant to understand that each of negative mitsvot has a spectrum and is not an idea only. In Torah, Orthodoxy and Orthopraxy ara alloyed which each other. When Tora prohibit to eat pig, the message is not "Pig is an abomination", but in each word of Torah, there is also a mean of though, that can lead to discover human bad behaviors ...
