Most mutations that cause cancer occur within body cells, and body cell mutations are not inherited. if cancer is not inherited, why does cancer statically appear to run in families? family members have similar genetic make-up that may make them predisposed to cancer. family members are exposed to similar environmental conditions. family members have a widely varied genetic make-up that can be affected by specific mutagens. family members share the contagious mutagens that can be passed by close exposure.

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?
