Zygosity Test

Well, the results are in! Your dad and I had a very strong opinion that you were fraternal twins. And, the results confirm that. We would have been shocked if you were identical!!

Evelyn - you have mastered rolling over and are doing it all the time.

Erin - you found your voice and are hooting and hollering all the time!

Today is your 4 month birthday - your dad and I are the luckiest people in the whole world!!

All my love,
Mom

We are pleased to report to you the results of the twin zygosity test that you requested. Analysis of the DNA indicates that Erin Lenore Detelfsen and Evelyn Grace Detelfsen are dizygotic, or more commonly referred to as fraternal 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 7-8 standard DNA markers (D5S818, D13S317, D7S820, D16S539, vWA, TH01, TPOX, and CSF1PO) and determined that the highly variable DNA markers were different for 2 or more markers between the twins. Thus, there is greater than a 99% probability that the twins are dizygotic.

As stated in our testing Terms and Conditions, these test results are not qualified for any medical or legal purpose. Please feel free to contact us if you have any questions about these test results.

Thank you for choosing Proactive Genetics.
