Asexual stick insects kept a key sex-linked gene system for 1 million years
Key Takeaways
- Researchers studied Timema stick insects that have reproduced asexually for about 1 million years.
- They expected dosage compensation, a sex-chromosome gene-balancing system, to have decayed.
- Instead, the system remained fully functional in rare males examined by the team.
- The result challenges assumptions that unused biological systems quickly erode.
