| uneven crossing-over | Unequal crossing-over, crossing-over that happens when the breaks do not occur at precisely homologous points in two chromatid strands, and hence results in localised duplication of genetic material in one chromatid and complementary deletion in the other. (05 Mar 2000) |
| flip-over disease | <disease> A disease of young, fast-growing broiler chickens which causes them to die suddenly with a short, terminal, wing-beating convulsion, whereby they often flip over and die on their backs. (05 Mar 2000) |

| four-strand crossing over | Crossing over with both strands of DNA from each sister chromatid, so that both strands from one chromatid are exchanged for both strands on the other. This is different from the usual case where only one of the two DNA strands on one sister chromatid is exchanged for the one matching strand (of the two strands) on the other sister chromatid.

A gauge for measuring the diameter of wire, thickness of sheet metal, etc, often consisting of a metal plate with a series of notches of various widths in its edge. A standard series of sizes arbitrarily indicated, as by numbers, to which the diameter of wire or the thickness of sheet metal in usually made, and which is used in describing the size or thickness. There are many different standards for wire gauges, as in different countries, or for different kinds of metal, the Birmingham wire gauges and the American wire gauge being often used and designated by the abbreviations B.
