occurs when a fetus gets an extra set of chromosomes from one of the parents. Triploidy is a lethal condition.

Is triploidy compatible with life?

The human genome has 46 chromosomes or two sets of 23. With triploidy, the fetus has a third set. Both triploidy and trisomy result in abnormalities that can be severe, but triploidy is not compatible with life whereas with some types of trisomy, like Down syndrome, the baby can live a long and healthy life.

How long do babies with triploidy live?

A baby born with triploidy may survive outside of the womb for a few hours or as long as five months. According to Unique, a charity for rare chromosome and gene disorders, the longest known survivor of triploidy lived for 10.5 months before having a seizure.
