SHOCK AS COUPLE DISCOVER THEY ARE BIOLOGICAL TWINS AFTER DNA TEST IN THE US.

A married couple in the US was thrown into utmost shock after a DNA test revealed that they are biological twins.

DailymailUK reports that the couple had been trying to conceive. It was when they visited a fertility clinic, and were going through a vitro fertilisation process that the doctor discovered there are too many similarities in their DNA profiles.

NAIJ.com gathered that the twins had been separated at a young age after their biological parents died in a car accident. They were adopted by two different families, in which none of them knew their adopted child had a twin.
