you have about a 1 in 60 chance of having natural 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.
Having two amniotic sacs, known as a "double" or "dual" amniotic sac, can occur when a woman is pregnant with multiples (e.g., twins). Each fetus typically develops its own amniotic sac. This situation is more common in dizygotic (fraternal) twins than in monozygotic (identical) twins.
No, twins are not normally attracted to each other. In most cases, twins have a close, supportive relationship as siblings but do not experience romantic or sexual attraction towards each other. Attraction between twins is not a common or normal occurrence.
It is not common for identical twins to have their periods at the exact same time. Menstrual cycles can be influenced by a variety of factors such as stress, diet, and lifestyle, which can cause variations in the timing of periods even among twins.
Identical twins are twins that develop from same egg. These twins have same genome, also they have same physical appearance with minimal differences.
I would say that if as long as you can remember your family has been having twins, triplets, ect. I would say it runs through your family's blood.
The most common gender in identical twins is both twins being female.
Fraternal twins are more popular.
Yes, it is common for twins to have two separate sacs in a pregnancy, known as dichorionic diamniotic twins.
Yes, it is possible. It would be more common if the twins are fraternal that only one twin would be affected by the disease because it is a recessive trait, meaning both parents must be a carrier for the offspring to be affected. If the twins are identical and the tay-sachs gene is present, then boths twins will be infected because identical twins have identical DNA
yes
Yes, horses can have twins, but it is not very common.
The are twins
Looks......?
In the US, the incidence of fraternal (dyzygotic) twins is 32 in 1000 live births.
A set of twins (2 babies) is called twins. Seven sets would still be twins. 7 babies born together (not twins) would be called septuplets.
If they were not then they would not be called identical twins!
