"When peace, like

Simply stated mosaicism is when an embryo, or person, is composed of two or more genetically different cell types. Depending on the chromosome involved, and the proportion of abnormal cells, mosaicism could lead to embryos that cannot implant, that miscarry or that result in pregnancies with abnormalities (mosaicism confined to the placenta has been associated with abnormal growth of the fetus).”
So I think basically the part tested that yields the abnormal result/has the abnormal cells becomes the placenta and the membranes and the part that becomes the baby could be just fine. Someone please do a better job of explaining this than I just did!
