An apple plant has two dominant alleles for red apples rr if it is crossed with another plant that has recessive genes for green apples rr what percentage of the offspring will have red apples assuming random chromosome segregation

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?
