Forward mutation
WebForward mutation is the mutation from wildtype allele to the detrimental allele. Backward mutations undo the forward mutation. Because there are many ways to destroy the function but fewer ways to undo that harm, backward mutations are normally more rare than forward mutations. What causes induced mutation? WebForward mutation Reverse mutation Frameshift mutation In Drosophila having red eyes is the wild type phenotype. Other eye colors are considered mutants. In a population of flies with white eyes, a single-base substitution is discovered that produces mutants with red eyes. What kind of mutation is this? Expert Answer The answer is option b.
