They can be. While identical twins always have to be the same gender, fraternal twins usually are not. However this is not always the case. Identical twins occur because they inhabit the same egg.

Mirror image twins are identical and have mirror image differences but are genetically identical which means they have the same DNA. A set of mirror-image twins will have similarities like a mole.

Yes. Conjoined twins are always identical (monozygotic) twins, and identical twins are always the same sex.There is a theoretical case where identical twins could be opposite genders, when the babies are female but in one of the females, a branch of one X chromosome breaks away; however, I don't believe this has ever been observed.

Everybody says that when there are twins one of the twins is supposed to be left handed and the other one right handed but I saw some signing videos and the both John and Edward write with the right hand but probably one of them used to be left-handed but was forced in some way to write with the right hand :)So now they are both right-handed :)

If one of your twins is right handed and the other left handed could they still be identical?
No. They both have to using the same hand. Identical means everything is the same. Yes, they would still be 'Identical' twins. No two human beings are exactly identical; even identical twins have different fingerprints and different life experiences. One of the pair was born first, was held by mother, father or the nurses first. They can have radically different personalities. I know of a pair of identical twins who are completely different from each other. The oldest is taller, bigger, more athletic, has more scars and is closer to his father. The other twin is smaller, quieter, more interested in his studies and prefers to stay in the house around his mother. You have to stand them next to each other and compare their facial features to even realize that they're twins.
