Aneuploidy represents the most prevalent form of genetic instability found in human embryos and is the leading genetic cause of miscarriage and developmental delay in newborns . Telomere DNA deficiency is associated with genomic instability in somatic cells and may play a role in development of aneuploidy commonly foun... | Human eggs ( oocytes ) are exceptionally prone to the erroneous acquisition of too few ( monosomy ) or too many ( trisomy ) chromosomes during development ( meiosis ) .
