Who can participate?
Twins are siblings resulting from a multiple pregnancy. They are born simultaneously and may sometimes bear a strong resemblance to one another; however, not all twins necessarily have the same physical appearance.
The twin test allows for the comparison of their genetic profiles to determine whether they are "identical twins" (monozygotic) or "fraternal twins" (dizygotic).
This test can be conducted using the DNA of two or more twins, particularly in the case of a multiple pregnancy. The DNA of the parents is not required, as the comparison is made directly between the genetic profiles of the twins.
Conversely, it is unnecessary to perform a twin test between ordinary siblings: as they do not originate from the same pregnancy, they cannot share an identical genetic profile.
The Real Twins
Identical twins come from a single fertilisation between an egg and a sperm. The resulting embryo then splits into two, giving rise to two foetuses that share exactly the same genetic makeup.
They are always of the same sex – either two girls or two boys – and are also known as identical or monozygotic twins.
Fraternal Twins
Fraternal twins result from the fertilization of two different eggs by two distinct sperm cells during the same cycle. They develop separately in the uterus and share, like regular siblings, about 50% of their DNA.
Known as fraternal or dizygotic twins, they can be of the same sex or different sexes, and generally exhibit less similar physical characteristics than identical twins.
We offer our services in partnership with Endeavor DNA Laboratories. The tests are conducted exclusively by this certified laboratory, to which you will send your samples directly after placing your order.
