Identical twins are also known as monozygotic twins, meaning they originate from a single zygote that splits into two identical embryos. Dizygotic twins (A) are fraternal twins, meaning they originate from two separate eggs fertilized by two separate sperms. Fraternal twins (B) are also dizygotic, but not all dizygotic twins are fraternal. Concordant (D) refers to a similarity or agreement between two or more individuals, but it is not specific to twins.
