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 can have the same blood type, but it is not always guaranteed. Blood type is determined by genetics, and twins may inherit different alleles for blood type from their parents. While it is common for identical twins to have the same blood type, there are cases where they may have different blood types due to genetic variations.

∙ 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.

∙ 15y 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 ;)

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.
What are facts about identical twins?
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.
How many egg cells are used with twins?
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.
Do your children have to have same blood as you?
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.
Can blood type 0 plus and blood type b plus have a?
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.

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.
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.
Can siblings with same birth mothers but different birth fathers have the identical blood type?
yes sibblings wih
