Yup. My twin is an A and I am a B (done by the military, twice to double-check). We look and talk alike. Sound alike.

How is a fraternal twin different than other twins?
Fraternal means "brother-like." Identical twins result from a single fertilzed egg dividing into two separate embryos so the twins share all DNA. Fraternal twins result from two different eggs being fertilized by two different sperm at the same time. The babies are then born at the same time, but only share 25%of their DNA with each other, which is the same amount that siblings born at different times share. The word fraternal used in social organizations, like "the fraternal order of"...refers to the thought that the members are like brothers to each other. Modern french uses the word frere to mean brother.
What does the initials rh stand for in blood types?
Rh factor is named after the Rhesus monkey which was the source of testing. It refers to the plus or minus after one's blood type which determines compatibility.
What is the difference between negative and positive blood types?
Negative and Positive blood types refer to the presence of the Rhesus D (RhD) antigen. Rhesus is the second main blood group typing after the A,B,O system. e.g. AB+ means the blood cells have A and B and RhD antigens present on the blood cell surface. O- means that A and B and RhD antigens are not present on the surface of the blood cell.
What types of receipients can receive Type B blood?
Type O or type A broadly speaking. it also depends on other proteins found on the surface of donated blood cells such as rhesus proteins. someone can be rhesus plus or rhesus minus meaning they either have the protein or don't. You can only receive blood of the same rhesus type of as your own for example: A rhesus positive can only receive A rhesus positive or O rhesus positive
Are there any blood types besides A B D and RH?
There are several different ways of 'grouping' blood. One system has blood groups A, B, AB and O. Another system is the rhesus grouping where a blood is classified as rhesus-positive or -negative; D and Rh are the same group. It is a combination of these 2 classificatons which is used most commonly. These are the most commonly known groups, but there are 28 additional systems that are recognised around the world.
How many different kid of twins are there?
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.
How may types of twins are there and which type may have different sex?
There are two types of twins -- monozygotic ("identical") from a single egg, and dizygotic (fraternal) from two eggs. Only dizygotic twins can have a different sex.
What are the three types of twins?
There is Identical twins, Nonidentical twins and Conjoined twins.
What kinds of twins are there?
Identical and Fraternal There are identical and fraternal. Fraternal twins happen when 2 different embryos start growing at the same time, so you get a brother and a sister or 2 sisters or 2 brothers that are the same age. Identical twins happen when 1 embryo splits into 2 embryos when it is only a few cells big, so both babies have the same genes.
How do twins look exactly alike?
They do look different! Even identical twins, with identical DNA, are different. Most have a slight difference in height and weight. Many people have a difficult time telling them apart because they are focusing on the wrong things. If someone looks only at the hair, they may not see that their faces are slightly different.
How many different types of babies can you have?
boy, girl and simese twins Siamese twins are now properly called conjoined twins. You can have identical twins[ same sex] , fraternal twins [ one male , one female ]. triplets, same way, quadruplets, quintuplists , sextuplets and so on , with fertility drugs.

Are there any twins?
Identical twins are formed when an egg fertilised by a sperm splits in half to form two different embryos.
What is a brother who has the same mother but different father?
If it is in the same menstrual cycle, it is called superfecundation. If it is later in the pregnancy it is called superfetation. They would still be fraternal twins even with different fathers (that is, half-siblings). This is known as heteropaternal superfecundation. More unusual are "semi-identical twins". These "half-identical twins" are hypothesized to occur when an unfertilized egg cleaves into two identical attached ova and which are viable for fertilization. Both cloned ova are then fertilized by different sperm and the coalesced eggs undergo further cell duplications developing as a chimeric blastomere. If this blastomere then undergoes a twinning event, two embryos will be formed, each of which have different paternal genes and identical maternal genes. More interesting is what the mother of these types of twins would be called.
How can you improve the chances of having twins?
There are two primary types of twins, Identical and Fraternal. Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins. Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older.
Karl Landsteiner figured out the types of this and co-discovered the Rhesus factor Types of what?
Blood
Can 2 sisters have O positive and O negative blood types and have the same mother?
If their mother and father had different Rhesus factors, yes.
