Perform a Twin DNA testing at New Jersey Centers helps you determine whether you and your twin, or your twin children, are identical.
It’s not as easy as it seems to know for sure whether twins are identical. It is usual to hear some questions about twins, like are your twins identical or fraternal?
Without a doubt, this is a question all parents of look-alike twins get every time they go for a walk or while they are packing up the extra-large diaper bag at the supermarket. If your parenting life is double-the-fun, you may think you already know the answer to that question. But do you really?
In a nutshell, only twins DNA testing can tell you for sure whether they’re identical or fraternal. Unless an ultrasound showed that your babies shared a single amniotic sac.
What is a Twin DNA Testing?
A Twin zygosity DNA testing can positively confirm whether twins are identical or fraternal related. This type of test compares the twins’ DNA profiles in order to see whether they match.
When performing Twin DNA Test at DNA Testing New Jersey, its simple and streamlined. Our accredited technicians collects DNA samples quickly and painlessly by rubbing a swab inside the mouth against the cheek. It’s as easy as brushing your teeth and can be done easily and safely on twins at any age, even newborns.
Furthermore, the collection kit can be sent directly to your home, or else we can arrange an appointment for you for sample collection at one of our hundreds of collection sites across the country.
Although, more than 70% of Dichorionic Diamniotic (Di/Di) twins are fraternal, they can also be identical. An exact match in the DNA test proves they are identical.
Let’s see the difference between fraternal and identical twins.
Twins categories: a quick debrief
Before we define extensively the Twins DNA testing, it is necessary to specify what it means being a fraternal or identical twin.
Medical professionals (and therefore parents) assumed that, if twins had their own amniotic sacs and their own placentas, then they must be fraternal. Not so fast!
- Fraternal twins: come from two eggs being fertilized by two sperm. The zygotes implant separately, have their own in-utero “condos,” and can be girl/girl, boy/boy, or boy/girl.
- Identical twins come from a single fertilized egg that splits in two. This division happens usually around days 4 or 5, and after the placenta and amniotic sac have started developing.
Note: If the fertilized egg splits before the placenta and amniotic sac normally start forming for identical twins. Say around days 2 or 3, then each zygote develops its own sac and placenta.
As a result of it, what could look like fraternal twins to medical pros is actually a set of identical twins!
How It Works
- DNA Testing New Jersey sends DNA-collection materials, swabs, and directions to test participants (or to their parents, if they are minors).
- Buccal (cheek) swabs are used to collect the DNA from each participant. It’s non-invasive, fast, and pain-free.
- The customer mail samples back to the lab where they are tested and analyzed by our team of PhDs. And in just a few days, the report is posted to a secure online account for viewing.
A probability of relationship is given for twins DNA testing, just as it is for paternity results. Except in this case the probability is for whether the twins are identical or fraternal.
Reasons to get a Twin DNA Test in New Jersey Centers
- To confirm the truth about a twin relationship
- Medical and/or health reasons
- Lost medical records about zygosity
- To put to rest doubt that may have arisen because of the twins’ physical characteristics as they age
Innovations in DNA Twin Testing
DNA Testing New Jersey has successfully developed a DNA test to to identify genetic differences between identical twins.
Up until now scientists could not distinguish the DNA of one monozygotic twin from the other. Still, the basic idea of mutations within the genotype of monozygotic twins had been in the heads of many scientists for a long time already. These mutations, they assumed, could render a discrimination between their DNA possible.
Ultimately, it is due to our colleagues here at DNA Testing New Jersey that a DNA test for a genetic discrimination between monozygotic twins has now been successfully developed.
Currently, this DNA test being used by police authorities and courts for a genetic fingerprinting to solve crimes involving monozygotic twins.
Facts about Twins
Here are some quick, fun, facts about twins:
- 1 in 90 live births are twins
- If you are a fraternal twin, you have a 1 in 17 chance of having twins yourself; but if you’re an identical twin, your chances of having twins are the same as for non-twins
- One-third of all twins born in the U.S. are identical
- The average birthweight for a twin is 5 lbs 5 oz
- Children of identical twins are genetically half siblings
- If identical twins were to marry other identical twins, their children would technically be cousins, but their DNA relationship would be that of full siblings
Final Thoughts
With today’s advances in DNA science, there is absolutely no good reason to wonder whether or not twins are identical or fraternal.
As they get older and their brotherly bond deepens, Argon and Aldridge will be thankful that their parents had this test done on their behalf.
There are many reasons mothers and fathers choose to have a Twin DNA Test in New Jersey. If you may be sure of the parentage of your child, state aid programs, insurance companies, and social security. A Twin DNA Testing can resolve questions from curiosity to financial or legal disputes.
The decision on whether twins are fraternal or identical is usually based on the Doctor’s examination of the placenta after delivery but this method is not always completely reliable.
Nowadays, with the new technologies we can perform a simple DNA test on twins (Identical Twin Test) by collecting loose DNA cells from the inside of the cheek using a buccal swab. This is a painless procedure that can be easily administered on infants as well as adults. Then, the DNA sample is analyzed and produces the donor’s genetic profile.
If the twins are monozygotic (identical), their genetic profiles will be exactly the same and if the twins are dizygotic (fraternal), their genetic profiles will be different. It is therefore possible to determine with 99% certainty whether twins are identical or fraternal.
