Do conjoined twins have the same sex?
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.
Are monozygotic twins opposite sex?
No, monozygotic twins would be the same sex. Monozygotic twins come from one single fertilized egg, or zygote, which then splits to create two separate zygotes which will be genetically identical, or "identical twins", which will always be of the same gender.
Why can fraternal twins be different genders but identical twins are are the same gender?
Identical Twins are the result of a single fertilized egg spliting in two producing two genetically identical children. Fraternal twins are the result of the mother producing two eggs each fertilized by a different sperm from the father. This can result in opposite sex twins.
How are twins born non-identical?
Non-identical (fraternal) twins are born when two separate eggs are fertilized by two separate sperm. This results in siblings with different genetic makeups and physical characteristics. Non-identical twins can be the same sex or different sexes.
Does 2 sacs and one placenta mean fraternal twins?
I am pretty sure because that is how my twins are at the moment that one placenta and two sacs mean identical twins more often than fraternal and more often identical if they are the same sex

What is the different between identical twins and franternal twins?
The DNA of identical twins and of clones is, apart from random, environmentally produced mutations, 100% identical. The only difference is that clones are produced on purpose through advanced bioengineering techniques while identical twins happen as an accident of nature. Identical twins are, in a sense, natural clones.
Can identical twins be of different sexes?
They can be. While identical twins always have to be the same gender, fraternal twins usually are not. However this is not always the case. Identical twins occur because they inhabit the same egg. Fraternal twins because two eggs were fertilized at the same time. So fraternal twins could be the same gender, but usually they are of the opposite gender.
What are twins of opposite sex called?
siblings
If twins aren't identical what are they called?
Twins who are of the opposite sex or do not look alike are fraternal twins ~ not identical. This means that at the time of their conception ~ two eggs were fertilised. In the case od identical twins, one egg is fertilised and split in half.
Why can fraternal twins be different genders but identical twins are are the same gender?
Identical Twins are the result of a single fertilized egg spliting in two producing two genetically identical children. Fraternal twins are the result of the mother producing two eggs each fertilized by a different sperm from the father. This can result in opposite sex twins.
Do identical twins have to be the same sex?
Yes. Identical twins come from one fertilized egg that has been split in two. Therefore, whatever sex the single egg would've been, the twins will be.
Is it possible of same sex children in non identical twins?
Yes.
Are fraternal twins never the same sex?
Fraternal twins can be the same sex or opposite sexes. It doesn't matter.
What are twins that dont look alike caled?
Fraternal. They develop from separate ova and are not genetically identical, so look different, can have different sex etc. Unlike "identical twins."
