In maize, a Ds or Ac transposon can cause mutations in genes at or near the site

Question

In maize, a Ds or Ac transposon can cause mutations in genes at or near the site of transposon insertion. It is possible for these elements to transpose away from their original site, causing a reversion of the mutant phenotype. In some cases, however, even more severe phenotypes appear when these What might be happening to the transposon or the nearby gene to create more severe mutations? Check all that apply. overexpression of the nearby gene insertions in the nearby gene chromosome breakage deletions in the nearby gene

Explanation / Answer

The correct option is insertions in nearby gene.When a transposon gets inserted in a nearby gene it renders it inactive or can modify its function thereby producing bizzare mutations.Mutations caused by transposons can be more deleterious and pronounced than those caused by chemical muatgens.
