It is a non-inherited condition and totally random, until and unless one of you have any chromosomal abnormalities associated with chromosome 18. The chromosomes are the inheritance unit of living organism on which the genes are located. During the process of germ cell division- meiosis 1 or meiosis 2 uneven distribution of chromosome (known as nondisjunction) causes the abnormal distribution of chromosomes. Besides trisomy 18 other trisomies like trisomy 21 or trisomy 13 can also be encountered using the method. In addition to this, a new age genetic test is also now utilised for screening of present condition which we will discuss it in this part later. She was told her newborn could die within days.

During the process of meiosis of germ cells, the event called non-disjunction results in uneven distribution of chromosomes causes trisomy. In numerical chromosomal alteration, these numbers are changed called aneuploidy. So if your doctor or genetic counsellor advice for abortion; calmly think on it.
