It is known that the gene responsible for development of blood groups according to AB0 system has three allele variants. If a man has IV blood group, it can be explained by the following variability form:
- A. Mutational
- B. Combinative
- C. Genocopy
- D. Phenocopy
- E. Phenotypic
Hint
Consider how alleles received from the two parents can come together in one genotype, and whether the DNA sequence itself had to change or the environment had to act.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
