They were conceived naturally, and Amy has spoken about the challenges and joys of raising twins, especially as a mother with dwarfism. The twins have since grown up and pursued their own paths, including careers in television and business.

There is no such thing as "semi-identical" twins. If fraternal twins each take a paternity test, only the real father would show up as the father.
Yes, it is possible. It would be more common if the twins are fraternal that only one twin would be affected by the disease because it is a recessive trait, meaning both parents must be a carrier for the offspring to be affected. If the twins are identical and the tay-sachs gene is present, then boths twins will be infected because identical twins have identical DNA
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
