Yes, in both cases.
Non-identical twins are more like normal siblings. Identical twins have the exact same DNA, so will be very similar in appearance. Their environment will cause them to have very slight differences, such as different fingerprints and freckles.
Identical twins, due to the fact that the one fertilized egg splits, have identical DNA. Fraternal twins, since they are from separate eggs, have different DNA.
Because the mother identical twins each have a different husband . . . half of his characteristics show up in their babies.
Fingerprints are different in identical twins.
there are two types of twins-- fraternal and identical. Fraternal twins are genetically unique, and they usually have physical differences. Identical twins are identically identical, such as a clone, and have exact physcial characteristics, excluding weight and scars etc.
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)

I dont think there is such a thing as paternal twins...perhaps you are thinking of fraternal twins. In that case, they are not identical twins, they do not look the same and they can be different sexes.

No, fraternal twins do.
Yes EVERYBODY has different DNA even if you are identical twins.
Fraternal twins occur when two fertilized eggs are implanted in the uterine wall at the same time. When two eggs are independently fertilized by two different sperm cells, DZ twins result. The two eggs, or ova, form two zygotes, hence the terms zygotic and biovular.Identical twins occur when an egg splits into two; which makes them identical. Identical twins are not hereditary like fraternal twins can be. It is complete coincidence.
fraternal twins have two different chromosomes
Paternal Non-Identical fraternal twins
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
The reason why some twins are identical and some are not starts in utero. Identical twins occur when one egg is fertilized and it splits to create two embryos. Nonidentical twins come from different fertilized eggs.
