It is known that the gene responsible for development of blood groups according to AB0 system has three allele variants. Existence of the IV blood group can be explained by the following variability form:
- A. Mutational
- B. Combinative
- C. Phenotypic
- D. Genocopy
- E. Phenocopy
Hint
Decide whether blood group IV needs any change in the DNA itself or only a particular pairing of alleles that already exist and are passed on by the parents.
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.
