Question

How can identical twins be distinguished with forensic serology?

Answer 1

For example, there are chemical marks on our DNA that help to control which genes should be turned on where and to what level. These epigenetic marks are added and removed over our life time in response to our specific set of experiences. This is true for all of us including identical twins. Interpret it.

Answer 2

identical twins don't have the exact same chromatic make-up, the chances of a meteor hitting the earth within the next 60 seconds are higher than someone having the same chromatic make-up, hope this helps
