Same egg Twins = identical twins, twins from different eggs = fraternal twins, the identical twins basicly are a result of 1 fertile egg that splits too far apart in early stage with the result twins... Since identical twins come from the same fertilised egg their base DNA is the same to begin with....don't have the expertise, but heterozygotic twins can also be born from the same egg, which then splits, so they have the same genetic heritage as the mother plus what they get from the father, so 50% + x
