Which of mendel’s laws states that alleles for different traits are sorted into sex cells separately?

Which of the following is a testable hypotheses?

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?

Which step is the same in both forms of fermentation, as well as in cellular respiration?
