Answer:
The inheritance of ABO blood groups corresponds to an autosomal codominant pattern.
Explanation:
The blood type is defined by the presence of surface antigens in the red blood cell, called A and B. The presence of each antigen is determined by a gene present on the parental chromosomes.
- Blood type A corresponds to the presence of gene A, and its genotypic expression can be A/A or A/O.
- Type B blood, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen.
- AB blood -due to codominance- has one gene for A and another for B, with genotype A/B.
- Blood type O, characterised by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.
The presence of an antigen A or B, suppresses the expression of blood type O, recessive, which will be possible only in its homozygous form.
