Identical Twins

At conception the egg from the female is fertilized by one sperm cell from the male. When cell division occurs this will divide into two new cells. These two new cells will then develop into two separate individuals. As a result the DNA from these two individuals will be identical.

Fraternal Twins

Fraternal twins are the result of two eggs being independently fertilized by two different sperm cells. As the DNA in the two different eggs and sperm cells are different, this will result in twins that are not identical. These all called fraternal twins.

This test determines the DNA profiles of the twins. If the profile is identical then a probability of them being identical twins is calculated.
