Are all conjoined twins same sex?
No, not all conjoined twins are the same sex. While most conjoined twins are identical and share the same sex due to their identical genetic makeup, there are rare cases where conjoined twins can be fraternal, resulting in one twin being male and the other female. The occurrence of conjoined twins is quite rare, and the sex combination can vary depending on the type of twinning that occurs.
What kind of creature always gives birth to same sex twins?
Certain species of reptiles, such as some types of lizards, are known to give birth to same-sex twins. This phenomenon can occur due to environmental factors or genetic predispositions that influence sex determination. Additionally, some studies have indicated that certain mammals might also exhibit this trait under specific conditions, but it is less common. Overall, the occurrence of same-sex twins is more frequently observed in reptiles.

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.
