Results of genetic fingerprinting to confirm the preimplantation genetic origin of newborn DNA.
a 1st polar body DNA based fingerprinting illustrating a match between transferred embryo #1 and newborn B, and transferred embryo #2 and newborn A. The cutoff of 40 % is indicated with a black bar and is based on previous publication [
15]. Similarities below 40 % are considered a match and above a sibling.
b Trophectoderm DNA based fingerprinting illustrating a match between transferred embryo #1 and newborn B, and transferred embryo #2 and newborn A. The cutoff of 50 % is indicated with a black bar and is based on previous publication [
16]. Similarities above 50 % are considered a match and below a sibling. In each type of fingerprinting, transferred embryo #1 was the one which possessed reciprocal aneuploid polar bodies, and was the oocyte/embryo that matched newborn B. Embryo #3, 4 and 5 served as known sibling control embryos since they were not transferred
