вЂњFor example, an AO mother will have blood type A, and a BO father will have blood type B. So if a woman with OO alleles has a baby with a man who has BB alleles, the baby will have a B blood type.Д¬an a baby ever have a blood type different from its parents? вЂњItвЂ™s certainly possible,вЂќ says Deva Sharma, MD, MS, a hematologist-oncologist at Vanderbilt University Medical Center in Nashville, Tenn. The O allele is considered recessive, which means itвЂ™s not always expressed. Your blood type is inherited from your parents-and you canвЂ™t change it anymore than you can change your eye color.Д®ach parent contributes one of their two A, B, or O alleles (a form of a gene) to a babyвЂ™s blood type. What about the rest of the blood types? The Stanford Blood Center provides these statistics. and Western Europe, O positive is the most common blood type, as is having a positive Rh factor. According to the book Blood Groups and Red Cell Antigens, blood type B is common in people in Asia while blood type A is common in Central and Eastern Europe. How common or rare a blood type is varies by race, ethnic background, and what part of the world you live in. This is extremely rare, occurring in only a handful of people worldwide. A very small number of people have whatвЂ™s called Rh null blood (also called gold blood), meaning it has no Rh factors at all. For example, some people have A positive blood while others have A negative. And people with an O blood type have neither A nor B antigens.Д®ach of those types are further broken down based on their Rh factor. Some people have both A and B antigens, giving them AB blood. If you have B antigens, you have a B blood type. If your blood has A antigens, you have an A blood type. Blood is typed according to an ABO blood group system. Again, blood types are based on the antigens (or lack of them) found on your blood cells and whether or not your blood contains the Rh D factor. The vast majority of people have one of eight blood types. From typing to transfusing, hereвЂ™s what you need to know about your blood and your health. Healthy blood is essential for a healthy life. Mixing one type of blood thatвЂ™s incompatible with another-thanks to things like antigens and Rh factor-can be fatal. If your blood lacks it, you have a negative blood type.Д¬ategorizing blood according to type is important for things like blood transfusions, which replace blood thatвЂ™s lost through surgery, accidents, and bleeding disorders. If your blood contains the Rh D factor-the most prevalent and important of the Rh factors-you have a positive blood type. Blood is further classified by its rhesus factor (aka, Rh factor). These are proteins and other molecules present on the outside of your red blood cells they determine what type of blood you have. Your plasma contains antibodies, which are substances your immune system uses to fight foreign invaders like germs and bacteria. And thereвЂ™s plasma, which provides the body with things like nutrients and hormones. There are platelets, which help your blood clot. There are red and white blood cells, which carry oxygen and help fight infection, respectively. If all you know about your blood is that itвЂ™s red, you have some catching up to do.Д«lood is made up of a lot of different components.
