what are the phenotypes for blood types?
608568
The possible human phenotypes for blood group are type A, type B, type AB, and type O. Type A and B individuals can be either homozygous (IAIA or IBIB, respectively), or heterozygous (IAi or IBi, respectively).

The three formed elements of blood are: white blood cells (leukocytes), red blood cells (erythrocytes) and platelets (thrombocytes ).

Blood cells are produced by bone marrow. The three major types of cells in the blood are red blood cells, white blood cells, and platelets. Red blood cells determine blood type and are responsible for transporting oxygen.

The five main types of blood cells are basophils, neutrophils, eosinophils, monocytes, and lymphocytes.

People with type A blood have anti-B antibodies. People with type B blood have anti-A antibodies. Type O blood contains both types of antibodies. The 2 steps above can accurately determine your blood type.

It's part of our DNA. Sometimes there's a change, or mutation, in DNA. “These different blood types evolved as a result of genetic mutations, but what caused certain blood types to be more successful is likely exposure to infectious diseases or other environmental pressures,” Fyfe-Johnson said.

['AA = A blood type.', 'AO = A blood type.', 'BB = B blood type.', 'BO = B blood type.', 'OO = O blood type.', 'AB = AB blood type.']

The universal blood type is O negative (O-). Donors with type O- blood have the unique power to help anyone in need of a blood transfusion. Red blood cells from O- donors can be transfused to anyone, regardless of the person's blood type.

However, in the United States, AB-negative is considered to be the rarest blood type, and O-positive the most common. The Stanford School of Medicine Blood Center ranks blood types in the United States from rarest to most common as follows: AB-negative (.6 percent) B-negative (1.5 percent)

Hematological parameters such as red (RBC) and white blood cell (WBC) counts and hemoglobin (Hb) concentration are tightly regulated traits with high clinical relevance. Values outside normal ranges are diagnostic for disorders, including cancer, immune diseases, and cardiovascular disease.

Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type. There are three common alleles for this trait, which can be represented by the letters A, B, and O. As shown in Table below, there are six possible ABO genotypes but only four phenotypes.

Dogs have more than 12 blood groups, and their red blood cells may contain any combination of these since each blood group is inherited independently. The most important of these is called Dog Erythrocyte Antigen (DEA) 1.1. Typing of blood donors and recipients is done before transfusion.

The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

Within the ABO system, people can be one of four groups: O, A, B, or AB; with respect to Rh a person is either positive or negative. This creates a total of eight main blood types. ... Those who have this "Rhesus" factor on their red blood cells are considered Rh positive. Those who lack the factor are called Rh negative.

If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative.

In general, there are three major types of anemia, classified according to the size of the red blood cells: If the red blood cells are smaller than normal, this is called microcytic anemia. The major causes of this type are iron deficiency (low level iron) anemia and thalassemia (inherited disorders of hemoglobin).

The five main types of blood cells are basophils, neutrophils, eosinophils, monocytes, and lymphocytes. Basophils are the cells mainly responsible for allergic reactions. They defend against parasites and bacteria by excreting two chemicals: heparin and histamine.
