3) white paper
The best source for his research about the mechanism of the drug would be : A peer-reviewed research article in a scientific journal ( A )
A peer-reviewed research article would be a best source for his research because peer-reviewed articles are written and reviewed by colleagues in the same scientific field of study.
An article written by an author about how a drug will alleviate pain in dogs and cats and reviewed by his peers will contain detailed information on the mechanism of such drug, therefore this article will be very informative and helpful to the student.
Hence we can conclude that , The best source for his research about the mechanism of the drug would be A peer-reviewed research article in a scientific journal.

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.
