Rotifers are unusual in that they often reproduce by parthenogenesis (some species, indeed, can reproduce only in this way).
輪蟲并不普通，因為他們的繁殖方式是孤雌生殖（確實，一些物種甚至只有這一種繁殖方式）。

The barrier to parthenogenesis in mammals, it seems, is something known as genetic imprinting.
ECONOMIST: A “virgin birth” in mice
Past attempts to create live mice by parthenogenesis, for example by stimulating mature eggs with chemicals, have failed.
