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.
When i say i love you tom wont hardly say it back what can i do.
Conjoined twins are always the same sex. They are identical twins.
Conjoined twins cannot be bred. This condition is not genetic.A set of male conjoined twins fathering children with a set of female conjoined twins will almost certainly produce children who are not even twins at all.
The most famous (Chinese) conjoined twins were the Siamese twins
conjoined twins are very very very rare .
why can't conjoined twins be brothers and sisters
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.
The twins were conjoined when they were born.
Yes, it's possible for a mutation in the chromosome to produce otherwise-identical twins with opposite genders. But generally no, identical twins have the same gender. (but fraternal twins have different genders just as often as any siblings)
There are several websites that have photos of conjoined twins. Zimbo has a section for them as well as the WellSphere site. The media gallery of USA Today has a photo retrospective section of different conjoined twins dating bask to 1930. Environmental Graffiti has a limited but impressive selection of photos.
fraternal twins have two different chromosomes
Conjoined twins are categorized by a set of adjectives ending with the suffix "-pagus" from the Greek word for "fixed". Early teratologists such as Ambroise Pare and Geoffrey St. Hillaire were among the first to identify and name the various types of conjoined twins. Many actual sets of twins do not fit perfectly into any of these classifications, and the terms are often combined to describe these twins.
