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.

The main 'job' of the endocrine system in most animals is to moderate and send out chemicals that affect other organs, tissues, and organ systems of the body.
