what is a mutant gene?
A. A mutant gene is a gene with a DNA sequence that has been changed from the DNA sequence of the wild-type version of the gene. The changed DNA sequence often produces a change from the wild type phenotype. 3. Add this to end of the definition of wild type: “The standard against which a mutant gene is compared to determine whether the mutant is dominant, recessive, or codominant.” This will allow deletion of the footnote below the definition of codominant.
