Type O Blood Heredity

November 07, 2020

Your blood type is just a description of which antigens you have. The a and b genes are dominant and the o gene is recessive.

Blood inheritance abo blood type.

Type o blood heredity. The abo blood group system is determined by the abo gene which is found on chromosome 9. Your children would have a 50 chance of having type a blood the ao genetic type and a 50 chance of having type o blood the oo genetic type. Science at this very time is attempting to create a synthetic rh negative o blood but without.

Note the only way the result will be type o with no other possibility is when both parents are homozygous. Blood types a and b are called codominant alleles they share in the controlling influence of our genetic blood make up while o is recessive a codominant allele is apparent or dominant even if only one is present. Table 1 blood group inheritance from parents to offspring.

Since blood type o is recessive it is not. Everyone has an abo blood type a b ab or o and an rh factor positive or negative. This marker is only used for genetic differences.

The first group gives us the letter or letters of your blood type and the rh status gives the positive or negative part a o ab etc. Blood type o is the most common of the blood groups. A recessive allele is apparent only if two recessive alleles are present.

The 4 pairs of alleles in smaller font are the genotypes based on the parental alleles. So it was a 1 in 4 chance for your daughter to be type o certainly not a rarity. That should reassure your husband.

Type o blood is double recessive. Genetic combinations of abo blood groups. With a mother having ao blood and the father having oo blood the possible combinations are ao ao oo and oo.

Also read about o negative blood type. O positive blood type is rh positive. There was a 25 chance she d get two o genes making her blood type o.

Each biological parent donates one of two abo genes to their child. And there was a 50 chance she d get an a and an o 25 for getting an a from each of you again making her blood type a. When we separate the o types into negative and positive we find that o negative the universal donor blood constitutes less than 7 of the world s population.

Though there are many groups of antigens the main two groups we talk about when it comes to blood type are abo and rh. Tendency towards higher levels of stomach acids. Figure 1 the image above illustrates the codominant inheritance of abo blood groups.

This can happen because of higher levels of stomach acids. If type o blood courses through your veins then you have a lower risk of developing coronary heart disease. Individuals with blood type o may be predisposed to certain medical conditions like ulcers.

The four abo blood groups a b ab and o arise from inheriting one or more of the alternative forms of this gene or alleles namely a b or o. Just like eye or hair color our blood type is inherited from our parents. Also if you wish to improve your physical and emotional health the solution is quite simple regular brisk exercise.
