Non-identical (fraternal) twins are born when two separate eggs are fertilized by two separate sperm. This results in siblings with different genetic makeups and physical characteristics. Non-identical twins can be the same sex or different sexes.
I have not seen any studies on whether twins are more likely to have an autism spectrum disorder than single-birth children. It is possible that no one has done research on this. If one identical twin has an autism spectrum disorder, there is approximately a 90% chance that the other identical twin will. They might not have the same autism spectrum disorder or they might have the same disorder at different levels of severity. Many studies show the chance that they both have it if one twin does as somewhere between 82% and 97%. If the twins are fraternal (non-identical) twins and one has an autism spectrum disorder, the other has about the same chance of having an autism spectrum disorder as non-twin siblings do, which is greater than the chance of having an autism spectrum disorder in a family that does not have any history of it.
Non-identical twins are when 2 sperm cells fertilize two different eggs during the same pregnancy.
Fraterna twins, or dizygotic twins, develop when two separate eggs are fertilized by two different sperm. Each twin will have its own genetic makeup and placenta.
Non-identical refers to items or entities that are not the same or do not share identical characteristics. This term is often used to describe objects, individuals, or concepts that differ in some aspects, such as appearance, features, or qualities. For example, in genetics, non-identical twins (fraternal twins) are those that develop from separate eggs and sperm, leading to variations in traits.

Siva has an identical twin brother called Kumar, and Jay has a non-identical twin brother called Tom
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
Fraternal twins.
it's possible but twins are rare
In identical twins, the development of the placenta is usually shared, meaning they both share one placenta. In non-identical twins, each twin typically has their own separate placenta.
I'm not sure on the actual percentages. It firstly depends on if your father is an identical or non-identical twin. (Maternal or fraternal) Non-identical (fraternal) twins are the hereditary type, not the identical ones. Identical twins are simply a hiccup with the cell division during fetal growth, whereas non-identical twins are due to the hereditary tendency of the woman releasing more than one egg at a time. The gene for non-identical twins is directly passed from fathers to daughters, and the chance of having twins usually skips a generation too (like baldness in men!). So, if your father is a twin (a non-identical twin) and you are his daughter, it's possible that you may also have twins, but it's far more likely that your daughter will. My father is a twin (his brother died at birth and it's not known if he was maternal or fraternal unfortunately) and I only have 1 child (a daughter). She has a very high chance of having twins if dad was fraternal.
dizygotic or non-identical twins
Where one cell splits into 2 or 3 durning the early age of pregnancy
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.
Absolutely not ! The only way for a woman to bear twins is if either there are two eggs implanted after conception (non-identical twins) or one egg develops into two embryos (identical twins)
