No. The chances of them being the same sex are the same as if they were not twins at all.

How may types of twins are there and which type may have different sex?
There are two types of twins -- monozygotic ("identical") from a single egg, and dizygotic (fraternal) from two eggs. Only dizygotic twins can have a different sex.
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.
What combination is needed to cause the development of dizygotic twins?
Dizygotic twins arise when two separate oocytes (eggs) are fertilized simultaneously by two separate sperm cells. No more genically identical than normal siblings. They have separate placenta and membrane. They can be of differing sex and have very different features
Can seperation of embryo developeing into 2 separate cells have to be the same sex?
Yes, this results in monozygotic twins, which are always the same sex.
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.
Can conjoined twins be different gender?
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.
Are fraternal twins never the same sex?
Fraternal twins can be the same sex or opposite sexes. It doesn't matter.
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.
If a boy and a girl are twins are they faternal twins or twins?
Twins can only be identical if they are the same sex. If they are boy and girl, they are fraternal.
What is having a embryo with two similar parts?
When you have an embryo with two similar parts, this means that there will be identical twins. They are formed when a single egg are split into two. Identical twins will always be the same sex.
Why are identical twins always the same gender?
fraternal twins have two different chromosomes
Was Shakespeare's twins identical?
No. All identical twins are the same sex. Judith and Hamnet were opposite sexes, and so were fraternal twins.
