So the real question is how the public feels about crossing the line between medical treatments for existingpeople and irreversible genetic alterations that would be passed on to future generations through genetic modification of the human germline (the sequence of germ cells,such as sperm and eggs, containing genetic material that a child may inherit).
因此真正的问题在于公众对跨越原有医疗界限，并将通过改造人类生殖细胞（精子和卵子等生殖细胞序列，包含子女可以继承的遗传物质）传递给子孙后代的不可逆转的遗传改变作何感想。
