There is no precise percentage of fraternal or identical twins but it is estimated that 2/3 of all twins are fraternal where as 1/3 of twins are identical.

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 having twins if your dad is a fraternal twin and you are a identical twin and your moms dad is a fraternal twin?

The probability is the same as if you had no history of twins in your family. There is no genetic component with identical twins, it is just something that happens. Fraternal twins occur if a mother "drops" two eggs in one month. Your father being a fraternal twin does not make you "drop" more than one egg in a month and so does not increase your chances of having twins. Your maternal grandfather being a fraternal twin did not effect your mother's ability to drop more than one egg and so did not effect your ability to "drop" more than one egg and so does not increase your ability to have twins.


If the probability of getting identical is 0.004 while the probability of fraternal twins is 0.023 then what is the probability that a person chosen at random will not be a twin?

1- P(identical) - P(fraternal) =1-0.004-0.023 =0.973 The probability of being a identical or fraternal twin plus the probability of not being a twin has to add to 1. so 1- probability of being twins=probability of not being a twin ;-)


If the probability of getting identical twins is 0.004 while the probability of fraternal twins is 0.023 then what is the probability that a person chosen will be a twin?

P(twin)=P(identical)+P(fraternal) P(twin)=0.004 +0.023 P(twin)=0.027 [That's 27 out of 1,000 cases, or 54 persons out of 1027.]


What is the probability of having twins if your dad is a twin?

I'm not sure on the actual percentages. It firstly depends on if your father is an identical or non-identical twin. (Maternal or fraternal) Non-identical (fraternal) twins are the hereditary type, not the identical ones. Identical twins are simply a hiccup with the cell division during fetal growth, whereas non-identical twins are due to the hereditary tendency of the woman releasing more than one egg at a time. The gene for non-identical twins is directly passed from fathers to daughters, and the chance of having twins usually skips a generation too (like baldness in men!). So, if your father is a twin (a non-identical twin) and you are his daughter, it's possible that you may also have twins, but it's far more likely that your daughter will. My father is a twin (his brother died at birth and it's not known if he was maternal or fraternal unfortunately) and I only have 1 child (a daughter). She has a very high chance of having twins if dad was fraternal.
