Identical twins do have the same blood group, because they have the same DNA. One egg and one sperm create two people. Fraternal twins may not have the same, though they could, because they have different sets of DNA. Two different eggs, two different sperm, two different people.
Identical twins should. Mutations are the only exception. Semi-identical twins (whether this is possible is still argued) are more likely to have such. Fraternal twins might, but no more likely than siblings having the same blood type (which is, reasonably, common). Fraternal twins with different fathers are less likely to share a blood type, just as would appear with half-siblings. Then again, it is POSSIBLE for you to have the same blood type as your unrelated next door neighbor, but it is not likely. I am just telling you the probability of things.
Identical twins are formed when a single fertilized egg splits into two embryos during early development. They share the same genetic makeup, so they are always the same sex and look very similar. Despite their genetic similarities, identical twins can have different personalities, preferences, and traits due to environmental influences and individual experiences.
In the case of fraternal twins, two separate egg cells are fertilized by two different sperm cells. For identical twins, a single egg cell is fertilized by a single sperm cell, but it splits into two embryos during early development.
No, children do not necessarily have to have the same blood type as their parents. Inheritance of blood type follows specific genetic rules, and it is possible for children to have a different blood type than their parents depending on the combination of genes inherited from each parent.
Yes, a person with blood type O+ can receive blood from a donor with blood type B+. However, they can only donate blood to someone with the same blood type.

Identical twins (monozygotic) occur when a single egg, fertilized by a single sperm, splits into two identical halves. Two separate babies with identical DNA are formed. Identical twins are always the same sex and blood type. http://www.twin-pregnancy-and-beyond.com/identical-twins-or-fraternal-twins.html
No matter what blood type a suspect is, there are other people with the same blood type. So blood type does not positively identify any single person. By contrast, other than identical twins, no two people have the same DNA.

MonoZygotic Twins
DNA tests are used because they are more exact than blood tests. Many people can have the same blood type and cross types. Every person has individual DNA, except identical twins.
Same (or mostly the same) facial features ("looks"), same blood type, and same eye color.
Cara and Mady Gosselin are faternal twins.
That depends on the type of twins. Fraternal twins usually have separate amniotic sacs. Identical twins usually share the amniotic sac.
Identical twins share the greatest genetic overlap as they are genetically identical. They develop from a single fertilized egg that splits into two embryos.
Identical twins share 100% of their DNA, meaning they have the same genes. The genetic material in identical twins is nearly indistinguishable, contributing to their physical resemblance and similar traits.
Yes particularly if your first set of twins are fraternal (aka non-identical twins) as these are the type of twins that are said to have a hereditary connection.
