Identical or fraternal? Telling the difference is not always easy but Who’zTheDaddy?™ offers you accurate and reliable twins DNA testing starting at just £139.
While this test can be used as a simple way to satisfy parents’ curiosity, it can also play an important role in situations where blood transfusions or organ donations are required, where DNA compatibility is a deciding factor. The twins DNA test is carried out by analyzing the samples provided using state-of-the-art genetic identification systems. These systems analyze 21 different genetic markers that result in minimum relationship probabilities of accuracy in excess of 99.99%.
Science behind the test
Identical (monozygotic) twins occur about once in every three twin pairs that are born. They occur when one fertilized egg splits up into two while it is still a tiny collection of cells. The same fertilized egg splitting into two means that each embryo will have the exact same genetic formation. Fraternal (dizygotic) twins occur when two separate eggs (ova) are released by the mother which is fertilized by two different sperm cells. This results in children with different genetic profiles. While twins may sometimes look identical to the naked eye, this is not always the case.
The Twin Zygosity DNA Test by Who’zTheDaddy?™ allows for a fast, reliable and simple way to establish the nature of the relationship shared by twins. The home DNA testing kit comes with two envelopes each containing a pair of cotton-tipped swabs which are used to collect the DNA samples. Once the swabs containing the samples are mailed back to the testing laboratory, results can be expected within 5-7 working days of the samples arriving at the labs. The cost of the twins DNA test by Who’zTheDaddy?™ is £139 and in the case of triplets or higher multiples, additional people can be added at a cost of £70 per extra person.
What other sibling tests do you offer?
If a twin zygosity DNA test is not exactly what you’re looking for, Who’zTheDaddy?™ also offers tests such as the Y-STR Male Lineage Test which is used to determine whether two male siblings share the same paternal lineage; or the X-SV female lineage test which can determine whether two potential siblings share the same biological mother.
