- wat10000 1y agoI don’t know much about it, but a source used by Wikipedia says: “It is also possible for a non-disjunction to happen after fertilization (about a 1-2% chance). In this case, some of the patient's cells are normal and some contain the extra chromosome. This is called mosaicism. Patients with this type of Down syndrome have milder symptoms.” https://www.medschool.lsuhsc.edu/genetics/down_syndrome.aspx https://www.medschool.lsuhsc.edu/genetics/down_syndrome.aspx
