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.

Does 2 sacs and one placenta mean fraternal twins?
No, 2 sacs and one placenta usually indicates the twins are identical, or monozygotic twins. Fraternal twins, or dizygotic twins, typically have separate placentas as well as separate sacs.
How are you most likely to get identical twins than fraternal?
Identical twins are more likely to occur from a single fertilized egg splitting into two embryos, resulting in genetic duplicates. Fraternal twins result from two separate eggs being fertilized by two different sperm cells. Identical twins are not influenced by genetics or family history, whereas fraternal twins can be influenced by both maternal and paternal genetics.
What are the 2 kinds of twins?
Generally fraternal twins are more common. For fraternal twins to occur twins must diverge, but differentiate upon becoming separate entities. Identical twins are rarer, in which the two siblings are of the same gender and are exactly alike upon birth. Rarer so are conjoined, or "Siamese" twins. This occurs when twins are born partially or extremely fused together. There is only a 25% survival chance for a conjoined twin. Most were only connected by gristle and flesh, and could have been easily separated easily, were they in modern society.
How do twins look exactly alike?
Twins can look alike due to sharing the same genetic material and inheriting similar physical traits from their parents. Identical twins result from a single fertilized egg splitting into two embryos, leading to nearly identical DNA. Fraternal twins, on the other hand, are the result of two separate eggs being fertilized by two different sperm cells, which can result in less resemblance between siblings.
Do twins have the same blood type?
Identical twins should. Mutations are the only exception. Semi-identical twins (whether this is possible is still argued) are more likely to have such. Fraternal twins might, but no more likely than siblings having the same blood type (which is, reasonably, common). Fraternal twins with different fathers are less likely to share a blood type, just as would appear with half-siblings. Then again, it is POSSIBLE for you to have the same blood type as your unrelated next door neighbor, but it is not likely. I am just telling you the probability of things.
Which is more common fraternal twins or identical twins?
Fraternal twins are more popular.
What are more rare fraternal or identical twins?
i say that identical twins are the least rare because like me a fraternal twin i only know 1 pair of fraternal twin.
Do Identical twins think more alike than Fraternal?
Yes. Fraternal twins don't look alike at all. Identical, meaning to look the same, are well, identical.
What is the difference between a fraternal twins and identical twins?
If two (or more) eggs are fertilised and develop together you will get fraternal twins. Identical twins are the result of a single fertilised egg dividing into two embryos.
Why do you think identical twins were more alike than fraternal twins?
Fraternal twins share most of their genetic material, by virtue of having the same parents. Identical twins, however, by definition share 100% of their DNA. This means, for example, that identical twins cannot ever be one of each gender, as fraternal twins often are.
Compared to frateral twins identical twins are much more similar in extraversion or neuroticism?
Identical twins are much more similar in both extraversion and neuroticism compared to fraternal twins. This suggests a higher genetic contribution to these traits in identical twins due to their identical genetic makeup, whereas fraternal twins share only about 50% of their genetic material on average.
Does 2 sacs and one placenta mean fraternal twins?
No, 2 sacs and one placenta usually indicates the twins are identical, or monozygotic twins. Fraternal twins, or dizygotic twins, typically have separate placentas as well as separate sacs.
Is identical twins are more closely related than tyhe fraternal twins?
Yes. Identical twins started out as one egg and one sperm cell and are genetically identical. Fraternal twins come from two eggs and two sperm cells and are no more closely related than any other sibling.
How are you most likely to get identical twins than fraternal?
Identical twins are more likely to occur from a single fertilized egg splitting into two embryos, resulting in genetic duplicates. Fraternal twins result from two separate eggs being fertilized by two different sperm cells. Identical twins are not influenced by genetics or family history, whereas fraternal twins can be influenced by both maternal and paternal genetics.
Is the DNA in twins the same?
Twins can have very similar DNA, especially in identical twins who come from a single fertilized egg that splits into two. On the other hand, fraternal twins are no more similar genetically than any other siblings. Some slight genetic differences can arise due to mutations that happen after the initial egg fertilization.
What are the odds of having twins twice?
From what i know, if your twins are identical then you have no increased chance of having twins a second time. If your twins are fraternal, you are twice as likely to have twins again because fraternal twins are the result of more than egg being released and that is a genetic trate.
Can Tay-Sachs occur in 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
