Fraternal twins make up approximately 75% of the twin population and can be boy/boy, girl/girl, or boy/girl sets. Fraternal, or "dizygotic", twins happen when Mom releases two eggs (either at the same or different times during her cycle), and different sperm fertilize each egg. Fraternal twins share up to 50% of their genes, and are no more alike or different than any two siblings would be. The similarity between fraternal twins can be close to identical - there are many fraternal twins that look identical - even more identical than some identical twins!
Don't worry DW I'm sure there's a twin of you somewhere in the world.
