How may types of twins are there and which type may have different sex?

What combinations would be needed to cause the development of dizygotic twins?
Dizygotic twins, also known as fraternal twins, result from the release and fertilization of two separate eggs by two separate sperm. Therefore, the combination needed is for a woman to release two eggs during ovulation and for both eggs to be fertilized by different sperm, leading to the development of dizygotic twins.
What is the difference between dizygotic twins and monozygotic twins?
Dizygotic twins develop from two separate ova fertilized by different sperm at roughly the same time, they are also called fraternal twins. Monozygotic twins develop from one zygote that splits apart producing genetically identical zygotes; also called identical twins.
What is the frequency of monozygotic twins versus dizygotic twins following IVF?
