How does God feel about cross breeding? What is parthenogenesis, and what might be the reason for its existence? Can animals choose not to reproduce? Are we still obliged to refrain from eating the meat of “unclean animals”? Are we to refrain from eating meat altogether? Is it true that God does not care about oxen?
