Identical twins are always the same gender, either both male or both female. This is because they come from a single fertilized egg that splits into two embryos.
The most common gender in identical twins is both twins being female.
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.
fraternal twins have two different chromosomes
about 80% because most of the people i no are identical
Approximately 30 of twins are identical, also known as monozygotic twins.
The most common gender in identical twins is both twins being female.
fraternal twins have two different chromosomes
Homozygous means "the same egg." That refers to identical twins. Identical twins are always the same gender since they have the same chromosomes.
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)

Fraternal twins share most of their genetic material, by virtue of having the same parents. Identical twins, however, by definition share 100% of their DNA. This means, for example, that identical twins cannot ever be one of each gender, as fraternal twins often are.
Identical twins start out as one egg that for some reason splits in two, and both halves develops into individuals. Genetically, they have to be the same. They have the same DNA.

They would be fraternal twins. Identical twins are created when one sperm fertilized one egg, and hat egg then splits in two. Identical twins are always the same gender, while fraternal twins can be either gender, or a mix of the two.
