IDENTICAL!

We are pleased to report to you the results of the twin zygosity test that you requested. Analysis of the DNA indicates that Bailey Garvin and Netta Garvin are monozygotic, or more commonly referred to as identical twins.

We first isolated DNA from cheek cells from the swab kits that were returned to our lab. We amplified the DNA using a technique called PCR. Next, we analyzed 15 standard DNA markers used in human identity (D3S1358, TH01, D21S11, D18S51, Penta-E, D5S818, D13S317, D7S820, D16S539, CSF1PO, Penta-D, vWA, D8S1179, TPOX and FGA) and determined that the highly variable DNA markers were the same for both twins. Thus, there is greater than a 99.9% probability that the twins are monozygotic.
