Fraternal being when two eggs are independently fertilised by two different sperm cells meaning the DNA profiles will not be identical.

Common Questions

Who might want a twin DNA test

Parents naturally want to know all they can about their children, and with twins this includes their zygosity. The twins themselves may also want to find out more information about their genetic make-up and their similarities. Whilst the twins are still infants, it may be difficult to assess if they are identical based on physical features alone.


Do identical twins have the same DNA?

Identical twins have almost identical DNA, it was previously thought that the DNA was entirely identical. In 2013, scientists discovered a way to find subtle differences in their DNA which could prove vital in solving crimes and paternity cases that involve twins.
