Sister chromatids remain together in Anaphase I of meiosis due to the presence of cohesin complexes protected by the protein shugoshin.
<h3>What happens during Anaphase of meiosis?</h3>
- The anaphase of meiosis differs from that of mitosis.
- In meiosis, a specific cohesin complex is formed which is different from the cohesion proteins of mitosis.
- During the S phase, this complex is formed at the centromere of sister chromatids.
- At the start, cohesion complex is present throughout the chromosome arms and helps in the formation of synaptonemal complex joining the two homologs.
- However during Anaphase I of meiosis, the cohesion molecules are cleaved by separase in the arms region resulting in separation of homologous chromosomes.
- But the cohesin complexes at the centromeres of the sister chromatids is well protected by shugoshin protein which blocks the action of separase.
- Therefore the sister chromatids remain attached during the Anaphase I.
- At the end of metaphase II, the cohesin molecules at the centromeres lose the protection of shugoshin protein.
- Therefore, the separase proteins are able to cleave the cohesin complex, which allows the sister chromatids to separate at Anaphase II.

Answer:
They are capable of regenerating body parts
.
Explanation:
Ambystoma mexicanum or commonly "axolotl" is an amphibian that live in the Mexican basin and currently is in danger due to the destruction of its natural habitat. This species is used in scientific research because the axolotl is capable of regenerating lost parts of their bodies.
