Biologists classify specific traits as good or bad. For example, long tails in cats could be classified as good, and short tails as bad. True / False (circle)​

Nucleic acids offer variability because they contain alternate forms of genes called .

According to these anatomical structures which two animals are probably most closely related

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?
