ANSWER:Step 1 of 2
Fraternal twins, also known as dizygotic twins, occur when two separate eggs are fertilized by two different sperm. They share the same womb and are typically born at the same time, which means they are exposed to similar prenatal environments. Additionally, fraternal twins often grow up together and share similar familial and environmental factors.
