Fraternal twins are siblings who develop from two separate eggs fertilized by two different sperm, resulting in two genetically distinct individuals. While fraternal twin is the most commonly used term to describe this type of twin, there are several synonyms that are also used. Some of these include dizygotic twins, binovular twins, and non-identical twins. These alternatives describe the same biological phenomenon of two babies being born at the same time from different eggs and sperm. Regardless of the terminology used, fraternal twins are a unique and special type of sibling bond that comes with its own set of challenges and rewards.
