 `What is the probability of a female identical twin giving birth to identical twins?`
 ```Hello California7, According to the following article, identical twin women have only a 0.6% probability of having a twin birth. ?Women who are themselves fraternal twins have a 10% chance of producing twins, identical twin women have only a 0.6% probability of having a twin birth. Once a woman conceives twins, she has a 5% (that's one in twenty) chance of having twins again. There are no interesting parallels to these percentages among dads! A man who is a twin has the same probability of fathering twins as any other man.? Twins: DEVELOPMENT and LANGUAGE http://www.speech-language-therapy.com/mbc.htm This article claims that if you are a twin and if you are identical, it doesn't affect your chances, and they remain from 1 in anywhere from 38 - 90, depending on if fertility drugs are used or not. If You Are A Twin (Or Have Twins In Your Family): ?If you are a fraternal twin, you have a 1 in 17 chance of having twins. If you are identical, it doesn't affect your chances, and they remain from 1 in anywhere from 38 - 90, depending on if fertility drugs are used or not. If your mother is a fraternal twin, you may have a higher than average chance of twins. If you father is a twin and you are a female, it may slightly increase your chances. If your husband is a twin or has twins in his family, it doesn't affect your chances of having twins. If you have a parent that is an identical twin, your chance of having twins yourself are the same as anyone else.? http://www.threebluestars.com/multiples/2twinningrates.html ?The hereditary part of having twins isn't for identical twins, but for fraternal twins, where a woman ovulates two eggs rather than one. That would be passed through the mother's side of the family, not the father's. ? http://www.physicsforums.com/archive/index.php/t-14398.html ?If the mother is herself a fraternal twin, the chances of having twins increases about five-fold? http://web.archive.org/web/20041010040926/http://twinsmagazine.com/factsstats.html Search terms used: Probability of a twin having a twin birth probability of identical twin to have twins I hope the information provided is helpful!
