Question

n 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 elements excise from this site, due to events at or near the mutant allele. What might be happening to the transposon or the nearby gene to create more severe mutations?

Answer 1

Answer:

Deletion in a nearby gene, chromosome breakage, and translocation of the gene to a heterochromatic location.

Explanation:

Transposable components (TEs), also known as "jumping genes," are DNA sequences that moves starting with one area on the genome then onto the next, in some cases making or reversing mutation and changing the cell's hereditary character and genome size.  

At the point when the transposon is extracted from the original site, it may remove a portion of the gene sections alongside it. This prompts the presence of a serious phenotype. Transposable components can likewise cause chromosome breakage. On the off chance that the whole gene is moved alongside the transposon to a heterochromatic location, the gene gets silenced
