title: Meiosis: mouse eggs do their anaphase topsy-turvy.
abstract: The meiotic separation of sister chromatids in mature metaphase II mouse eggs is observed to depend initially on spindle lengthening (Anaphase B), then on microtubule shortening (Anaphase A). Having Anaphase B precede Anaphase A may be the mechanism by which mammalian eggs can generate a haploid chromosome number but without the loss of too much cytoplasm.
