Answer:
Co-dominance because he expresses both of the alleles simultaneously
Explanation:
The ABO blood group system is used by humans. This blood group type is controlled by multiple alleles. Alleles A and B are both dominant over allele O but are co-dominant. Co-dominance is a type of inheritance pattern in which two alleles of a gene both express themselves i.e. neither is recessive.
This is the case of this family whose parents have a genotype of AO (blood type A) and BO (blood type B) respectively. The children have blood types A, B, and AB. However, the child with genotype AB possesses both the A and B allele, which are both expressed in his blood group (phenotype), hence, it can be said that the child is exhibiting CO-DOMINANCE for the blood group trait.

Joint hypermobility syndrome (JHS) and Ehlers-Danlos syndrome, hypermobility type (EDS-HT) are the tissue disorders which can be characterized by chronic pain, joint instability complications, and minor skin changes. During these, Fatigue and headache are the very common symptoms; though they can be diagnosed using specific criteria.
JHS/EDS-HT is a rare common condition that could not be diagnosed by most clinicians and pain specialists, resulting in interventions like symptomatic and non-satisfactory treatments, because there is a lack of reasonable pathophysiologic rationale.
Pain, fatigue, and headache in JHS/EDS are usually treated with the help of certain symptoms or on the basis of doctors’ experience.
<span>Therefore, in order to the cure of such symptoms, doctors suggest pathogenic mechanisms. The major aim of the re-writing of the natural history of JHS/EDS-HT is to raise awareness among clinical geneticists and specialists treating chronic pain conditions about pain and other complications of JHS/EDS-HT.</span>
