Woman gives birth to her own grandchildren

A great percentage of Down syndrome cases are caused by one gamete (sperm or egg) having two copies of chromosome 21, producing an embryo with three copies of 21. If Down syndrome occurs in a surrogate baby, it's almost certainly due to the excessive chromosome from either of the parents.

Jam it back in, in the dark.
