Uniparental disomy

Humans ordinarily have two of each pair of chromosomes. This normal condition is termed disomy, and ordinarily one chromosome will come from the mother and one from the father.

If two consecutive abnormalities of reproduction occur, someone may inherit two copies of a chromosome from one parent and none from the other. This condition is called uniparental disomy.
