| Lyon hypothesis | <genetics> Hypothesis, first advanced by Lyon, concerning the random inactivation of one of the two X chromosomes of the cells of female mammals. In consequence females are chimaeric for the products of the X chromosomes, a situation that has been exploited in female Negroes (who are heterotypic for isozymes of glucose 6 phosphate dehydrogenase) as a means to confirm the monoclonal origin of papillomas and of atherosclerotic plaques.

| lyonization | The inactivation of an X chromosome. One of the two x chromosomes in every cell in a female is randomly inactivated early in embryonic development. Named after geneticist mary lyon. (12 Dec 1998) |
| Meltzer-Lyon test | A test used in diagnosis of gallbladder conditions: 25 ml of a 25% solution of magnesium sulfate are delivered into the region of the sphincter of Oddi through a duodenal tube, causing contraction of the gallbladder, relaxation of the sphincter, and the expulsion of bile from the common duct and gallbladder; bile from the common duct is relatively pale and is expelled first, that from the gallbladder follows; samples aspirated from the tube are examined for pus cells, pigment granules, epithelial cells, cholesterol, etc. (05 Mar 2000) |

| Lyonization |
A mechanism in mammals that allows them to compensate for X chromosomes in excess of the normal complement. The excess X chromosomes are cytologically condensed and inactivated, and they do not play a role in much of the development of the individual. The name derives from the discoverer of the phenomenon, Mary Lyon.
