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 ...
The Rambam (Kilayim 1:3) and the Shulchan Aruch (YD 297:2) explicitly rule that the issue of Kilaei Zeraim (planting mixtures of edible seeds (except grapes)) only applies in the Land of Israel and a Jew can even plant his own mixtures outside of Israel on purpose.
The Rambam writes (Hilchot Kilaim 1:4)
אין אסור משום כלאי זרעים, אלא זרעים הראויין למאכל אדם; אבל עשבים המרים, וכיוצא בהן מן העיקרין שאינן ראויין אלא לרפואה, וכיוצא בהן--אין בהן משום כלאי זרעים.
The prohibition of Kilei Zeraim (mixed seeds) only applies to seeds [of plants] which are human food. Bitter herbs and other herbs which are only used for ...
The Rambam (Kilayim 1:3) and the Shulchan Aruch (YD 297:2) explicitly rule that the issue of Kilaei Zeraim (planting mixtures of edible seeds (except grapes)) only applies in the Land of Israel and a Jew can even plant his own mixtures outside of Israel on purpose. So I think we can reason a fortiori that your friend is allowed to keep his vegetables when he ...
One question would be whether such an organ would be considered pig and thus forbidden to consume. (The title to your question perhaps suggests that this is the crux of the question, as it focuses on the transplant of the organ, not the creation of the organ. That being the case, I will focus on this question).
Even if it were, the (near) universal rule in ...
The prohibition not to sow your field with a mixture of seeds is called Kilayim.
PracticalHalacha describes how it prohibits from planting two species of fruit or vegetable plants (and trees) together in Eretz Yisrael (except for grapes which also applies outside). The prohibition covers all types of food-producing plants: herbs, vegetables, grains, trees. ...
Rambam writes (Maachalos Asuros 10:11-12):
ספק ערלה וכלאי הכרם בארץ ישראל אסור. בסוריא והיא ארצות שכבש דוד מותר.
כיצד היה כרם וערלה וענבים נמכרות חוצה לו. היה ירק זרוע בתוכו וירק נמכר
חוצה לו. שמא ממנו הוא זה שמא מאחר. בסוריא מותר ובחוצה לארץ אפילו ראה
הענבים יוצאות מכרם ערלה או ירק יוצא מן הכרם לוקח מהן. והוא שלא יראה
אותו בוצר מן הערלה או לוקט ...
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 ...
There is absolutely no problem with writing two such languages.
I was thinking maybe you can bring proof from the stones that Moshe rabbeinu wrote the Torah (or mitzvos) on in 70 languages (I think that is the plain meaning of "languages" although could be it refers to something else).
I think it was 12 stones (don't know for sure). Even if not I think the ...
I assume that you talk about Kilaey hakerem and kilaey zeraym. See Mishna Kilayim (8, 1):
כִּלְאֵי הַכֶּרֶם אֲסוּרִין מִלִּזְרֹעַ, וּמִלְּקַיֵּם, וַאֲסוּרִין בַּהֲנָאָה. כִּלְאֵי זְרָעִים, אֲסוּרִים מִלִּזְרֹעַ וּמִלְּקַיֵּם, וּמֻתָּרִין בַּאֲכִילָה, וְכָל שֶׁכֵּן בַּהֲנָאָה.
this mishna shows that Kilaey zeraym are allowed for profit and eating.
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 ...
A number of points:
Kilaei Zeraim applies to things that grow from the ground. Mushrooms do not qualify.
Kilaei Zeraim is forbidden only if you plant it intentionally OR if you leave it that after you find it and it grows to maturity.
Kilaei Zeraim requires at least TWO different types of seeds to be planted in addition to the vine itself.
