They are dizygotic. Fraternal twins.
No. The placenta produces and cleanses the blood for the fetus.
Identical twins may or may not share the same placenta . Identical twins develop when a fertilized egg splits. Depending on when the split occurs will determine if the twins share a placenta, with either one or two chorions and amnions, or if they each develop their own placentas.
False, the fetus and mother exchange nutrients via the placenta
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.
A covalent bond.
do identical or non identical twins share the same placenta
It means that the twins share the same placenta but different anemic sacs.
Twins that share a single placenta.
No. The placenta produces and cleanses the blood for the fetus.
Only identical (monozygotic) multiples share a placenta (and not all of those). If two or more of the sextuplets are monozygotic, those may share a placenta, with their fraternal siblings having their own. If by some astronomical odds a monozygotic - sextuplet pregnancy was possible I cannot imagine the pregnancy surviving long enough to deliver viable babies with only one placenta supplying all their needs - in addition the risk of cord accidents would be extremely high.
No the placenta produced and cleanses the blood fetus
The ultrasound can determine if they are fraternal or identical. If they are identical then they will share a placenta and they may even share an amniotic sac. If they are fraternal they will have separate placentas. Sometimes it is difficult to see because of the membrane but the ultrasound is sophisticated and they normally can tell.
