When a fertilized egg doesn't completely spilt to become twins which happens with identical twins of the same sex.
Answer
The process is a mystery of nature, but starts out as Identical twins-which according to fixed biological laws, take the same gender. Something goes wrong in the replication process, and the twins are conjoined or literally joined together there are various points of attachment.
In some extreme cases one can have a Y-Job, that is one basic body with two heads, this is true of the sisters now living in the midwest, they are blondes, with two heads, two hearts, three lungs, and other anomalies.
Conjoined twins are always the same gender, two boys or two girls. they start out as orthodox identical twins, and then the wrong buttons get pushed. There are some staggering variations, as four arms no legs and the bodies joined in the center with two heads at opposite ends like a ferry boat, which are rarely viable.
Answer
Conjoined twins are formed when twins are somehow deformed in the major body formation of childbirth and form themselves together.
When identical twins should be formed, the egg (zygote) does not fully split therefore creating conjoined twins.
Siamese twins or conjoined twins are formed when a single fertilized egg splits and develops into two individuals. These individuals are born with some of their body parts joined together.
twins are conjoined due to the egg not completely splitting inside the woman

Incomplete production or forming of normal twins. this also explains supernumerary appendages such as a Girl with Three arms I saw who worked in a department store. The third arm was short and stubby, but she had some control over it. a store in the same chain also had a camera vendor with only One arm, the shirt sleeve being tied back, it was strange.
Magic
When ordinary identical twins are created the egg splits in the womb and the two twins grow separately. In Siamese twins this does not happen properly and the two groups of cells (of each separate twin) grow around each other becoming fused forming a Siamese twin.
