So it seems from the above posts that the gender is not determined until 40 days but after 40 days the vlad is no longer considered maya bi’alma so the Chinese have no choice halachicaly but to take what Hashem gave them.
It was mentioned that by goyim it is considered a chiyuv misa but by a Jew it is not. Can someone please explain the difference. I assume that the issur by goyim is murder since that is one of their 7 mitzvos. What is the issur by Jews?
