Are fraternal twins less alike then identical twins?
Yes
Why do you think identical twins were more alike than fraternal twins?
Fraternal twins share most of their genetic material, by virtue of having the same parents. Identical twins, however, by definition share 100% of their DNA. This means, for example, that identical twins cannot ever be one of each gender, as fraternal twins often are.
Why are identical twins and fraternal twins not the exact same?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.

How do you know if two twins are identical or just fraternal twins that look a lot alike?
The only way to definitively determine if twins are identical or fraternal is through genetic testing. Identical twins share 100% of their DNA, while fraternal twins share about 50% on average, just like regular siblings. Physical similarities alone are not enough to distinguish between the two types of twins.
If twins aren't identical what are they called?
