| anaphase I | <cell biology> The stage in the first meiotic division of meiosis that follows metaphase I. The pairs of homologous chromosomes are separated from each other and moved to opposite ends of the cell. This stage begins as soon as homologous chromosomes begin separating and ends when the chromosomes arrive at opposite ends of the cell. (09 Oct 1997) |

| anaphase II | <cell biology> The stage in the second meiotic division of meiosis that follows metaphase II. In each cell produced during the first meiotic division, the paired chromatids are separated from each other and moved to opposite ends of the cell. The stage begins as soon as the centromeres connecting each chromatid to its pair break and ends when the two new sets of chromosomes arrive at opposite ends of each cell. (09 Oct 1997) |

| anaphylactic antibody | Antibody that has an affinity for certain kinds of cells, in addition to and unrelated to its specific affinity for the antigen that induced it, because of the properties of the Fc portion of the heavy chain. See: heterocytotropic antibody, homocytotropic antibody, cytotropic antibody test. Synonym: anaphylactic antibody, cytophilic antibody. (05 Mar 2000) |
