Trisomic rescue

From Wikipedia, the free encyclopedia

Trisomic rescue (also known as trisomy rescue or trisomy zygote rescue) a genetic phenomenon in which a fertilized ovum containing three copies of a chromosome loses one of these chromosomes to form a normal, diploid chromosome complement. If both of the retained chromosomes came from the same parent, then uniparental disomy results.
