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.

∙ 11y agoNot necessarily. If they were diamniotic dichorionic (two separate eggs were released, fertilised by different sperm resulting in each foetus having its own chorionic and own amnionic sac, thus two placentas ,etc), it's entirely possible that they could be different blood types. The older of my fraternal twin girls is A+ but the younger is O-.

∙ 15y agoWell you see fraternal twins are born by fertilization of two different sperms of the father with two different ova of the mother, therefore referred to as dizygotic. They share only 50% of their genetic markers. So the chances of each of the twins born, to have a particular blood group is not different than a normal child. So the only way you can predict the blood groups of each of the twins is by checking their parents' groups. And of course there is no relation between the blood groups of each children born.

∙ 10y agoYes. Same genetic make up then same blood type.
Wiki User
∙ 14y agoIt depends on what blood types the parents have. If they have the same blood type, most likely the twins will have the same. The opposite with different blood types.

∙ 14y agoYes, As They Have The Same Chromosomes But One Will Have An Improper Chromosoms Or Even More But The Blood Type Stays The Same Hypocrit ;)

What are facts about identical twins?
Same (or mostly the same) facial features ("looks"), same blood type, and same eye color.
Do twins have the same blood type?
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.
How many egg cells are used with twins?
It depends on the type of twins If It was identical (monozygotic) twins, one egg is fertilized (As you can see, identical twins have similarity in phenotype (the observable characteristic of an organism) because of development of one zygote divided into two embryos) but if it was non-identical twins, two eggs or more (such as triplets or quadruplets) are fertilized. The twins have differences in phenotype
Do your children have to have same blood as you?
No - children do not have to have the same blood type as the parents. For example, if one parent has blood type A and the other has blood type AB, the child might have A, B or AB blood types. (For the child to have B, the parent with blood type A would need to be heterozygous, Ao)
Does first born baby have same blood type as mother?
it depends on what the father's blood type is, there is a 50/50 chance that your child will have your blood type

What is The scientific name for identical twins.?
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
Why does DNA testing of blood lead to a more reliable match of blood to suspect than does blood typing?
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.
What type of twins have the greatest similarity in IQ?
MonoZygotic Twins
Why are DNA test carried out rather than blood test?
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.
What are facts about twins?
Same (or mostly the same) facial features ("looks"), same blood type, and same eye color.
Which type of twins are Cara and Mady Gosselin - identical or fraternal?
Cara and Mady Gosselin are faternal twins.
If you are an identical twin do you share a bag of fluid inside the mothers womb?
That depends on the type of twins. Fraternal twins usually have separate amniotic sacs. Identical twins usually share the amniotic sac.
Im a twin could you have twins?
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.
Can siblings with same birth mothers but different birth fathers have the identical blood type?
yes sibblings wih
Which type of twins develop from two fertilized eggs?
Twins from different eggs are fraternal twins. They are siblings with the same birthdate. They are twins, but not identical, and can even be girl and boy. It is the same process taking place as a single child that a woman becomes pregnant with, but the process happens with two children at the same time. The woman releases two eggs that month instead of one, and they both are fertilized. That is how this type of twin is produced.
