Abo blood types can be complicated to understand.

Inheritance blood type table. Visit this page to earn more about rh factor. Blood inheritance abo blood type. Thus there are 8 blood groups altogether.

We inherit our sex male or female and blood group from our parents. There are three alleles which determines the a b o blood groups in human. 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.

The most common by far is blood type o followed by type a type b and the least common is blood type ab. Revise genetic inheritance for gcse biology edexcel. Chart showing the possible blood types for offspring.

Table 1 blood group inheritance from parents to offspring. These will be expressed whenever the gene is present. There was a 25 chance she d get two o genes making her blood type o.

So it was a 1 in 4 chance for your daughter to be type o certainly not a rarity. Just like eye or hair color our blood type is inherited from our parents. Alleles are different possible types of a particular gene in this case the gene s controlling our blood type.

Inheritance of blood types. There are basically four primary common blood types. Within the abo blood group system the a and b genes are co dominant i e.

Each biological parent donates one of two abo genes to their child. The abo blood type of the father if the blood type of the child and the mother are known bottom chart. Otherwise a or b dominate or are codominant as type ab.

Note the only way the result will be type o with no other possibility is when both parents are homozygous recessive for type o. Blood type is determined by the alleles that we inherit from our parents. Genetic disorders can also be inherited.

The rh blood group system is attributable to two genes rhd and rhce which are located on chromosome 1 the rhd gene is dominant so the expression of the d antigen depends upon whether an rhd gene has been inherited from one or both parents. The a and b genes are dominant and the o gene is recessive. This is mostly due to the fact that the o type antigen is masked by the presence of an a or b type antigen.

That should reassure your husband. Inheritance of blood group. Therefore a person is considered to be d positive whenever the rhd gene is present even though the gene may have only been inherited from one parent.

Blood groups are inherited from our biological parents in the same way as eye colour and other genetic traits. It is named as rh factor because it was discovered from the rbc of rhesus monkey. Everyone has an abo blood type a b ab or o and an rh factor positive or negative.

Rh factor is a type of antigen which is found on the surface of rbc. The 4 pairs of alleles in smaller font are the genotypes based on the parental alleles.
