Yes. Conjoined twins are always identical (monozygotic) twins, and identical twins are always the same sex.There is a theoretical case where identical twins could be opposite genders, when the babies are female but in one of the females, a branch of one X chromosome breaks away; however, I don't believe this has ever been observed.
Nature has various safety valves. That is one of them. Conjoined Twins are identical twins with a natural connective bond, therefore they always take the same sex. Fraternal twins, like the fictional Bobbseys, can be Boy and Girl.
No. The chances of them being the same sex are the same as if they were not twins at all.
boy, girl and simese twins Siamese twins are now properly called conjoined twins. You can have identical twins[ same sex] , fraternal twins [ one male , one female ]. triplets, same way, quadruplets, quintuplists , sextuplets and so on , with fertility drugs.
They can be either but are always Gender-Bound, Two boys or Two girls, a Boy and a Girl, born Siamese is impossible, as they are identical twins, not fraternal and normally ( Take their Gender) to a man- or woman as it were.
Sure, I guess they would normally be legally considered two different people.But (whether married or not), they won't have much privacy for sex.
No. All identical twins are the same sex. Judith and Hamnet were opposite sexes, and so were fraternal twins.
Fraternal twins can be the same sex or opposite sexes. It doesn't matter.
Yes. Conjoined twins form when the fertilized egg starts to split, but does not completely split into two. Improved. There are no known cases of opposite sex Conjoined twins but that does not mean it can not happen. it is generally believed that identical twins means actually identical but the correct term now is actually monzygotic twins meaning one sack the reason they use this term is because to simply put it identical twins is actually rare when twins are born of the same sack Mono they are rarely actually identical and as such it is possible for a monozygotic twins to not completely sperate but in rare cases actual identical twins can in fact be of seperate sexual phenotype's they usually have some other defect
Twins can only be identical if they are the same sex. If they are boy and girl, they are fraternal.
Twins are caused on one of two conditions. The first possibility is that two eggs were released from the mother and both were fertilized. The second possibility is that one egg was penetrated simultaneously by two sperm.
Like the Chess rule: Queen takes her color, Siamese twins are always Identical twins- and these always take the same gender. One could not have a Boy and Girl Siamese twins. some for many years were either Brothers (Chang and Eng) or Sisters such as the Hilton sisters, the Gibb ( or Gibbs) sisters, etc. for obvious show-business reasons the distaff twins are preferable to the carnivals, etc. the Hilton Sisters were a stellar example. So the problem of toilet use does not occur- they are two girls, or two boys so go to either the Men's or women's rooms as the gender requires.
