Descriptor disomía uniparental
Entry term(s) disomía unipaternal
heterodisomía uniparental
isodisomía uniparental
Scope note: Presencia en una célula de dos cromosomas procedentes del mismo progenitor, sin que exista el otro cromosoma del otro progenitor. Esta composición cromosómica se debe a la no disyunción (NO DISYUNCIÓN GENÉTICA) durante la MEIOSIS. La disomía puede estar constituida por cromosomas homólogos de un progenitor (heterodisomía) o por un cromosoma duplicado (isodisomía).

RDF Unique Identifier: https://id.nlm.nih.gov/mesh/D024182
Scope note: The presence in a cell of two paired chromosomes from the same parent, with no chromosome of that pair from the other parent. This chromosome composition stems from non-disjunction (NONDISJUNCTION, GENETIC) events during MEIOSIS. The disomy may be composed of both homologous chromosomes from one parent (heterodisomy) or a duplicate of one chromosome (isodisomy).
