Karyotype explanation: There were actually two different karyotypes observed; the one before the "/" sign is from the fetus and is unbalanced (see below), and after the "/" sign is most likely from the mother (mat) as maternal cells are sometimes adhered to the fetal cells in a placenta. The mother's translocation is balanced, meaning that she has two copies of all regions of her chromosomes, even though two are rearranged. This is the concern in having children if one of the parents is a carrier of a balanced translocation. The numbers in brackets indicated the number of cells observed for each karyotype. A total of 20 cells were analyzed here. This type of karyotype is called "mosaic", meaning there were more than one cell line present in the sample.
