Most conjoined twins that I know of are of the same sex. I do not know of a set that is of the pposite sex.

uh... you must be the same gender to be a conjoined twin... i have actually seen conjoined twins of the same gender on tv about a dozen times...
"Monozygotic-- also known as identical -- twins form when a single fertilized egg splits into two embryos. This split can happen anytime after fertilization; as more time passes, the twins are more likely to share commonalities. If the split occurs more than twelve days post conception, the embryos do not fully divide and the twins may share body parts. Like all monozygotic twins, conjoined twins are always same sex (either both boys or both girls). It is estimated that seventy percent of conjoined twins are female."
they also share DNA, so that would be why they must be either male or female and not both...

I thought that all conjoined twins were of the same gender... :s On Not Another Teen Movie there are conjoined twins & they're female.

Conjoined twins are mono-zygotic (i.e. identical) twins, and it is in fact possible, though EXTREMELY rare, to have mono-zygotic twins of different genders. An XXY mono-zygote can develop a boy twin and a girl twin when the extra X chromosome forms in one twin and the Y chromosome forms in the other. Add the rarity of that occurance to that the odds of being conjoined, and the almost improbable odds of a mixed-gender conjoined twin pair become apparent.
In short, it is theoretically possible to have a boy-girl conjoined twin pair, but you have a much better chance of winning the lottery than seeing such a pair.

Yes, if they are identical twins they have the same sex. Then the genetic or environment problems that creates conjoined twins would still have the same chance to create same sex conjoined twins.
When a mother gives birth to two children they can be two separate children, but almost always they are twins, either of the same sex or of opposite sex. So most of the same sex conjoined twins you see are identical twins. They may not look like it because they aren't an equal blend, but genetically they are identical.
If you check out this article: http://en.wikipedia.org/wiki/Conjoined_twins
You will see an example of a pair of same sex conjoined twins.

Actually, I don't believe that it is possible for conjoined twins to be of different genders because the condition that causes them to remain connected is the fact that when the cell splits, it doesn't divide completely. So, this can only happen with identical twins since identical twins come from the same egg. Identical twins are the result of the one fertilized egg dividing completely to create 2 separate individuals. Fraternal twins, which can be either sex, come from two separate eggs being fertilized by two separate sperm.

Conjoined twins are ALWAYS the same gender and identical. This is because conjoined twins are the result of an egg splitting, but not doing so completely. When eggs split, identical twins are the result, and identical twins, of course, are always the same gender.

Yes it is entirely possible, in fact, most of the time, conjoined twins are the same gender.

yes actually it's more natual for the conjoined twins to be of the same gender, by the way 70-75% of conjoined twins are female.

Conjoined twins are monozygotic twins whose bodies are joined at the same time at beginning. this happens the position the only zygote of similar twins fails to split thoroughly. This situation takes position in about a million in one hundred,000 pregnancies. And them being monozygotic ability a unmarried egg is fertilized to form one zygote which then divides into 2 separate embryos. Monozygotic twins are genetically similar (except there has been a mutation in progression) and they seem to be a similar sex. in reality 3 situations were documented of mixed sex monozygotic NON-conjoined twins, so i imagine the probability of having them be both isn't plausible. i'm no longer a geneticist, besides the undeniable fact that it kind of feels really sparkling that it truly is no longer likely to ensue.

Most conjoined twins are of the same gender. I have never known of any who weren't.
