What is the difference between blood phenotype and genotype?
A phenotype consists of only those traits or antigens that can be directly typed, whereas a genotype is the sum of all genes a person has inherited within a blood group system.
What is genotype and phenotype in blood group?
The ABO blood group antigens are encoded by one genetic locus, the ABO locus, which has three alternative (allelic) forms—A, B, and O. A child receives one of the three alleles from each parent, giving rise to six possible genotypes and four possible blood types (phenotypes).
Is genotype the same as blood type?
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….Blood types and genotypes?
| Blood type | Possible genotypes |
|---|---|
| O | OO |
How do you determine the genotype of a blood type?
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.
Which blood group is best for marriage?
Based on these traits, the theory suggests these blood type matches are most likely to result in happy marriage:
- O Male × A Female.
- A Male × A Female.
- O Male × B Female.
- O Male × O Female.
What blood type is Bo?
Blood Type Inheritance
| Genotype (allele combination) | Phenotype (blood type) |
|---|---|
| AO or AA | Type A |
| BO or BB | Type B |
| AB | Type AB |
| OO | Type O |
Is there O+ blood type?
O+ is found in 38% of people, making it the most common blood type.
Can O+ and O+ have a baby?
That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. Each of their kids will also have a 3 in 8 chance of having A+, a 3 in 8 chance of being O+, and a 1 in 8 chance for being A-. An A+ parent and an O+ parent can definitely have an O- child.
What are the possible genotypes for blood type?
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.
What are the genotypes of O blood?
The people who have a blood type of O are those that have no antigens whatsoever. However, the OO types of blood genotype are the ones with both A and B antibodies. The antigens are found in the surface of the red blood cell proteins while the antigens are found in the blood plasma components.
What are the types of blood groups?
There are four main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents.
Which blood types are recessive?
However, type-O blood is recessive to both type-A and type-B. This is because type-O blood has no antigens, so if a person has the allele for either type-A or type-B blood, it will mask the presence of type-O blood. Within this system of three alleles, type-A and type-B can be co-dominant, but O is always recessive.
