Do feternal twins have the same germs?
Fraternal twins do not share the same placenta in the womb, so they do not share the same blood supply or amniotic sac. This means that they do not have the same germs. Each twin has their own unique immune system and biological makeup.
How Do Fraternal Twins Occur and Identical Twins Occur?
Fraternal twins (dizygotic twins) are simply two fertilized eggs that are implanted in the uterus at the same time. Identical twins (monozygotic twins) is one fertilized egg that separates into two embryos. In most cases, identical twins share one placenta, but have separate amniotic sacs. In some cases, they have two placentas. In rare cases, they share both the placenta and the amniotic sac.
What is combination of chromosomes XY for fraternal twins?

Fraternal twins are developed from the fertilization of two separate eggs. In most cases a woman releases one oocyte every month from alternate ovaries. Sometimes an oocyte is released from both ovaries at the same time both of which are fertilized by separate sperm. This results in the development of non-identical (fraternal) twins each having its own placenta for nourishment.
