Question 1

Will this test tell me if my twins are semi-identical?

Accepted Answer

Semi-identical twins are derived from the same egg but two different sperm. Normally, with DNA Twin testing, if the twins are identical twins, they will have exactly the same DNA profile, whereas if they are fraternal twins, their DNA profile will not be exactly the same. Semi-identical twins are genetically more similar than fraternal twins, but not the same as identical twins. If the twins are identical, the DNA twin test report will show conclusively that they are identical twins. If the twins are fraternal or semi-identical, the results will show that they are fraternal (non-identical) but will not distinguish between fraternal versus semi-identical.

Question 2

What do i do if they live in 2 different states?

Accepted Answer

All of the components in the Twin Test kit are individually barcode labelled so it would not be a problem for you to split the kit and send the other twin's supplies to them in the other state. You can collect your samples separately, and even send them back to the laboratory for testing separately. Because the kits are individually barcode labelled, the samples will still be tested together, even if they are not collected at the same time or at the same place.

Question 3

Does this tell you the possibility of conceiving twins like carrying the genetics or does it have to be when you're pregnant?

Accepted Answer

No, this test is for families to conclusively confirm whether a set of twins are identical twins or fraternal twins.

Question 4

Did everyone get identical test information? Our twin test every single test marker came back with the same info. are they always that identical?

Accepted Answer

I feel like most people testing likely think they have identical twins because if they looked completely different, there wouldn’t be much of a need to test. Ours are identical, and yes it should be so close because identical twins share 99.99% of the same DNA since they were a cell that split in utero. Fraternal is when 2 eggs were released and both were fertilized, so they have the DNA of regular siblings. So yes, identical twins should have all the exact same markers.
