Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive.

The presence or absence of A or B antigens gives us four main blood types: A type blood has only A antigens on red blood cells. B type blood has only B antigens on red blood cells. AB has both A and B antigens on red blood cells.

Normally, being Rh-negative has no risks. But during pregnancy, being Rh-negative can be a problem if your baby is Rh-positive. If your blood and your baby's blood mix, your body will start to make antibodies that can damage your baby's red blood cells. This could cause your baby to develop anemia and other problems.

The red cells in your blood can be A, B, AB, or O. ... Your blood can be Rh positive, which means that you have the Rh protein, or Rh negative, which means that you do not have the Rh protein. The letter of your blood group plus the Rh makes your blood type. You can be O+, O−, A+, A−, B+, B−, AB+, or AB−.

38% of the population has O positive blood, making it the most common blood type. O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+).

You can find out your baby's sex if you have noninvasive prenatal testing (NIPT), a blood test that can detect Down syndrome and a few other chromosomal conditions starting at 10 weeks of pregnancy.

5﻿ Monozygotic (identical) twins will have the same blood type, with a few very rare exceptions. Dizygotic (fraternal) twins may have the same blood type, or they may have different types.

You can now take a blood test as early as nine weeks into your pregnancy. This can reveal your baby's sex. Free cell DNA tests like Panorama work in pregnancy because your blood is carrying traces of your baby's DNA.

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

Distribution of blood types There are 4 main blood groups: A, B, AB and O, of which group O is the most common. In the United States, the average distribution of blood types is as follows: O-positive: 38 percent. O-negative: 7 percent.

Doctors classify blood types as A, B, AB, and O. ... For example, a person with O+ blood does not have A or B antigens on the surface of the cells but does have Rh factor. In contrast, O- blood has no A or B antigens and no Rh factor.

ABO Blood Type Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive.

A simple blood test that can determine a baby's sex as early as seven weeks into pregnancy is highly accurate if used correctly, a finding that experts say is likely to lead to more widespread use by parents concerned about gender-linked diseases, those who are merely curious and people considering the more ethically ...

What It Means to Have A Positive (A+) Blood Type. If your blood is A positive (A+), it means that your blood contains type-A antigens with the presence of a protein called the rhesus (Rh) factor. Antigens are markers on the surface of a blood cell.

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).
