What are the phenotypes and genotypes of ABO blood groups?
Table 4-5. Correlation of ABO phenotypes and genotypes.
| Phenotype | Possible Genotype |
|---|---|
| A | AA or AO |
| B | BB or BO |
| AB | AB |
| O | OO |
What are the possible genotypes and phenotypes?
Genotype & Phenotype. Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). With alleles ‘A’ and ‘a’ there are three possible genotypes AA, Aa and aa.
What are the 4 genotypes?
A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
What are blood phenotypes?
The “phenotype” of any blood group refers to which antigens are detectable on the RBC, and it usually (though not always) corresponds to the genes that the patient carries. For blood donors, to determine compatibility for a patient with an alloantibody. For blood donors, to identify donors with uncommon phenotypes.
What are the 6 genotypes of blood?
How many phenotypes are in ABO blood types?
The four basic ABO phenotypes are O, A, B, and AB.
How many possible phenotypes are there for ABO blood groups?
four possible phenotypes
The genetic locus, ABO locus encodes for the ABO blood group antigens. It has 3 allelic forms – A form, B form and O form. A fetus receives one of these three alleles from each of its parents. This produces four possible phenotypes (blood types) and six possible genotypes.
What are the 6 possible genotypes?
How many Abo genotypes are there?
There are three alleles for blood type, all of which are found on the ABO gene . Because each person has two sets of chromosomes, there are six different genotypes possible for this characteristic.
What is genotype of blood type ABO blood system?
The genotype would be C/c and their phenotype would be C and c – meaning both Big C and little c antigens are found on their RBC. ABO Blood Group there are 3 alleles that occupy 1 locus on each pair of chromosome #9, i.e. A, B and O. Remember that as offspring we inherit 22 chromosomes (autosomes) from mom and 22 chromosomes (autosomes) from dad.

What are some examples of a genotype?
An example of a genotype is an organism’s blood type, while an example of a phenotype is its height. Height can be affected by an organism’s poor diet while developing or growing up. A person’s genotype is the special allele combination that is in his or her genetic make-up.
