Twins who develop from two separately fertilized ova. Also called fraternal twins.
Twins who are not identical and not always of the same sex because they come from two different ova fertilized at the same time.
Two people born at the same time to the same parents after fertilization of two separate oocytes. They may be of different sexes and are no more likely to resemble each other than any other brothers or sisters.
Also known as fraternal twins, two babies that come from separate, simultaneously fertilized eggs. If one dizygotic twin develops MS, the other has the same genetic risk for MS (approximately 2-5/100) as any other sibling or first-degree relative.
Fraternal twins, otherwise known as nonidentical twins, are formed through the concurrent fertilization of two separate egg cells, also known as ovum. Each twin has its own placenta and they may be of different genders. This process is termed as Dizygotic twinning. This explanation is provided in the English language.
