In pea plants, the allele for smooth seeds is dominant over the allele for wrinkled seeds. A pea plant with smooth seeds is crossed with a pea plant that had wrinkled seeds. the results show 173 smooth seeds and 166 wrinkled seeds. Based on these results, the genotype of the smooth parent pea plant would be:

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?
