Identical twins are always the same sex; they usually are the same height, weight and have similar hair color. In relation to the genetic differences in MZ twins, different genes can be turned on or off which is why one identical twin may have a condition or disease that the other doesn’t.
Q. Do conjoined twins have the same DNA?
In fact, they have the same DNA! So no, conjoined twins with different fathers is not possible. The end result is not two separate, connected people but one person with a mix of both twins. Some of the chimera’s cells have the DNA of one twin and the rest have the DNA of the other.

Q. Why are Momo twins dangerous?
Monoamniotic twin pregnancies are susceptible to complications including cord entanglement, increased congenital anomalies, intrauterine growth restriction, twin-to-twin transfusion syndrome and increased perinatal mortality
Q. Does 2 yolk sacs mean twins?
A single gestational sac observed with two heartbeats indicates a monochorionic twin pregnancy. Two gestational sacs indicate a dichorionic pregnancy. Although there is some debate on this matter in the reproductive medicine community, typically, if there are two yolk sacs, the pregnancy is diamniotic
Q. Are MoMo twins genetic?
MoMo babies always have identical features and are of the same sex because they derive from the same gene set. No cases of the chromosomal abnormality that sometimes results in boy-girl sets of monozygotic twins have ever been identified in MoMo twins.
Q. Is it dangerous for twins to share a placenta?
In uncomplicated monochorionic twin gestations, the blood exchange between both babies is equal, and the placental mass is equally shared. But one-third of monochorionic twin pregnancies are at risk for complications when sharing between both babies is not equal.
Q. How common are MoMo twins?
What are monoamniotic twins? Monoamniotic twins occur when a single fertilized ovum (egg) results in identical twins that share a common placenta and amniotic sac. Monoamniotic twins are very uncommon, representing approximately one percent of identical twins and less than 0.1 percent of all pregnancies.
