Test for Twins

A DNA test for twins enables one to determine whether twins are identical or fraternal.

Identical twins come from the same ovule and sperm cell. When one egg is fertilized by one sperm cell, and then divides and separates, two identical cells will result. These cells will then develop into identical twins. The DNA for identical twins will also be identical. Additionally, the physical attributes of identical twins can be (but are not always) similar. They are always of the same sex.

Fraternal Twins: When two eggs are independently fertilized by two different sperm cells, fraternal twins result. The DNA profiles for fraternal twins will not be identical, and they are just like full-siblings born at different times. Furthermore, fraternal twins are not necessarily of the same sex.

Review by J.-C. Grace on the 20.04.2012: 6 out of 6 stars
My father was a fatherless child. My biological grandfather was unable or unwilling to admit that he had fathered a child. Meanwhile my biological grandfather and my father have passed. The question about my origin was still very important to me. I had carried out a Y-DNA comparison with the grandson of my grand-father's brother. The Genetic test has confirmed that he was my biological grandfather.

Very professional. The paternity test could be less expensive.

Review by M. Herch on the 13.01.2012: 5 out of 6 stars
At the age of 53 years, my suspicions were finally confirmed: My parents are not my biological parents. Even as a child, I doubted the story of my parents. The doubts were at that time drawn into the ridiculous. I couldn't convince my parents to carry out a DNA test. Fortunately, I am in a good relationship with my aunt (my mother's sister). With her help I was able to confirm that I am not the daughter of my mother. Although I still do not know who is my biological mother, the result was a redemption to me.
