I know of two ways. Maybe there are more, but first the egg is fertilized and then it splits, and second, two different eggs are fertiglized.
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.
Non-identical twins occur when the mother ovulates and two separate eggs are released and fertilised. This is different to identical twins, they occur when one original egg splits n two and develops in tandem. then yo have sex
Identical twins do not necessarily have to run in the family. Identical twins occur at random, when a fertilized egg splits into two embryos, and this can happen to anyone regardless of family history.
Female twins that are not identical are called fraternal twins. Fraternal twins occur when two separate eggs are fertilized by two separate sperm. Maternal twins refer to twins that share the same mother but can include both identical and fraternal twins.
No, fraternal twins are more common than identical twins. Identical twins occur when a fertilized egg splits into two embryos, resulting in two individuals with the same genetic makeup. Fraternal twins occur when two eggs are fertilized by two different sperm, resulting in siblings who share approximately 50% of their genetic material, like regular siblings.
The likelihood of having twins varies depending on factors such as genetics, age, and ethnicity. On average, twins occur in about 1 in 30 births. Factors such as fertility treatments, family history of twins, and maternal age can increase the chances of having twins.
Whether the dam was a twin herself may have a little influence on her odds of giving birth to twins. Normally twins occur in one out of 1000 births.
No, twins in the same placenta are not genetically identical. While identical twins share the same DNA, they may have slight genetic differences due to mutations that occur after fertilization.
No, non-identical twins are fraternal twins. They are created when two eggs are fertilized at the same time and become embryos. Identical twins are when a fertilized egg splits into two on its own.
In y professical opinion as a doctor in the Orillia Soldiers Memorail hospital i believe that therev is no know or proven way to conceive twins. The best chance of twins is if it genetic or within your spouces or partners family, also taking any medication while pregent can form conpatuis babies
Yeah. Twins are known to occur but are pretty rare.
There are two primary types of twins, Identical and Fraternal. Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins. Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older.
