You mean like Siamese twins? Yes it is possible but only with identical twins I think because they come from the same egg thing and the egg thing splits on two and if they haven't split in two entirely by the time the babies are born they are joined together =(
Conjoined children can be connected at any body part. So yes, they can be conjoined by testicles.
they wanted to be a big company so they joined together
Well im a dr so i can tell you that your son can not have any twins! its just impossible!
some twins have some genetic or psyonic link that makes them want to stay together
Interested in music and art so he joined them together
Of course, anything is possible. But, most usually, twins skip generations. So, a twin may be the grandparent of twins, rather than the parent.
Fraternal twins are different eggs and sperm so they are like regular brother and sister except they are born together
Because usually when you have conjoined twins their side by side or back to back. So where would it go? But maybe its possible.

Fraternal twins do not necessarily write with the same hand. Hand preference is influenced by genetics and environmental factors, so it is possible for fraternal twins to have different dominant hands.
they can... it is possible and has happened before but its VERY VERY unlikly. so ussually no
Yes, it is possible. But you won't be able to name them. Example: Boy and Girl. It's really stupid I haven't seen any twins of the same sex so I can't answer any questions about that. Happy Simming!
