| Glossary Term | Uniparental Disomy |
| Definition | The inheritance, in a diploid organism, of both copies of a single chromosome from one parent. This may result from the union of a gamete bearing two copies of one chromosome with a gamete bearing no copy of that chromosome, or from the union of a gamete bearing two copies of one chromosome with a normal gamete, followed by the loss of one chromosome through an error in mitosis. Because of imprinting, uniparental disomy can have phenotypic consequences in mammals. See, for example, Prader-Willi Syndrome. |
