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.
I am pretty sure because that is how my twins are at the moment that one placenta and two sacs mean identical twins more often than fraternal and more often identical if they are the same sex
Your friend is expecting fraternal twins, which means they developed from two separate eggs fertilized by two different sperm. In this case, one twin is male and the other is female, sharing one placenta but each having their own amniotic sac. This scenario is not uncommon among twin pregnancies.
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.
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.
If two fraternal twins have the XY sex chromosomes, they will be male.
Yes, twins can share a placenta during pregnancy. This occurs when identical twins share a single placenta, while fraternal twins each have their own placenta.
Yes, fraternal twins can share a placenta if they are from the same fertilized egg that split into two embryos.
Yes, fraternal twins can share one placenta during pregnancy.
Yes, twins can have separate placentas. In cases of fraternal twins, each baby typically has its own placenta. However, in cases of identical twins, they may share a single placenta.
Yes, fraternal twins can share a placenta if they are from the same fertilized egg that split into two embryos. This is known as a monochorionic pregnancy.

No, twins can either share the same placenta (monochorionic) or have separate placentas (dichorionic), depending on whether they are identical or fraternal twins.
Your friend is expecting fraternal twins, which means they developed from two separate eggs fertilized by two different sperm. In this case, one twin is male and the other is female, sharing one placenta but each having their own amniotic sac. This scenario is not uncommon among twin pregnancies.
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.
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.
How do fraternal twins form? Answer one egg from each ovary is fertilized.
In identical twins, the development of the placenta is usually shared, meaning they both share one placenta. In non-identical twins, each twin typically has their own separate placenta.
