Does 2 sacs and one placenta mean fraternal twins?

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


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?

They do look different! Even identical twins, with identical DNA, are different. Most have a slight difference in height and weight. Many people have a difficult time telling them apart because they are focusing on the wrong things. If someone looks only at the hair, they may not see that their faces are slightly different.


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.


Psychologists use what to determine the role that heredity and the environment play in determining trait?

Psychologists like to use sets of identical twins for studies. If the identical twins turn out more similar than fraternal twins or regular siblings, they conclude that the trait is genetically influenced and hereditary.

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.

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.

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


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.

What is the probability of a twin to have twins?

if twins run in the family u are more likely to have twins but most likely fraternal because identical twins are just a very unique coincidence
