This was a research done by Hans Spemann, an embryologist of the early 20th century in Germany.
His research lead him to conclude that the dorsal and ventral (top and bottom) halves of the embryo were different. The top half contained a certain group of cells that organize development. They are visible on the dorsal surface of a 2-cell-stage embryo.
The outcome of his constriction experiments depended on exactly where this structure was in relation to the constriction. If one half of the constriction contained the entire structure, it would develop into an embryo that could live and the other half developed into the belly-piece.
If the structure was evenly split during the constriction, the result was twin, including Siamese twin, embryos. If it was split unevenly, it resulted (in some cases) an embryo with two heads (a Siamese twin).
He also inadvertently discovered a way to clone during this process of constricting embryos as they split.

Mine are also uneven. I was told that it was because of scoliosis. Maybe your muscles developed more on one side than the other because of an uneven posture. These are two possible reasons why they are uneven.
Is it possible to have unintentional twins after an IVF treatment?
Yes, it is. In many situations 2 embryo's will be transferred back into the mother's womb to double the chances of one or either actually hatching, though I suppose when you make that decision with your fertility specialist you will be aware of the chance both embryo's will hatch and you're willing to accept the risk (and joy!) of having twins. However even if only one embryo is transferred back, it can still split itself up resulting in identical or monozygotic twins. Rare, but possible!
