No one knows. conjoined twins have been around as long as humans have, more than one million years.The first famous confirmed case of conjoined twins were Chang and Eng Bunker.

No. Conjoined twins are always identical twins, and never just fraternal twins. Identical twins come from a single embryo that splits. In the case of conjoined twins, a complete split never occurs. So when they come from the same embryo, they are always the same gender.
In the development process, either the egg didn't completely split, or they joined together at some point. Typically conjoined twins share one or more body systems. Usually they have a common circulation system. Depending on what organs or systems they share, they may be able to be split apart.
I have an identical twin. For me it is no more likely that I will have twins than anyone else because identical twins are just flukes. If you are a non- identical twin and that is because your mother had two eggs, then you may have this too, and it is more likely you will have twins.
Generally fraternal twins are more common. For fraternal twins to occur twins must diverge, but differentiate upon becoming separate entities. Identical twins are rarer, in which the two siblings are of the same gender and are exactly alike upon birth. Rarer so are conjoined, or "Siamese" twins. This occurs when twins are born partially or extremely fused together. There is only a 25% survival chance for a conjoined twin. Most were only connected by gristle and flesh, and could have been easily separated easily, were they in modern society.
Yes. In fact, twins are more likely to have twins than "non-twins" are.
if twins run in the family u are more likely to have twins but most likely fraternal because identical twins are just a very unique coincidence
