The reason that sister chromatids remain together in anaphase I but separate in anaphase II of meiosis. Introduction: Meiosis results into the formation of four daughter cells and each of the daughter cell have half number of chromosomes than the parent cell. There are two meiosis processes namely meiosis I and meiosis II.

The reason that sister chromatids remain together in anaphase I but separate in anaphase II of meiosis.

Introduction:

Meiosis results into the formation of four daughter cells and each of the daughter cell have half number of chromosomes than the parent cell. There are two meiosis processes namely meiosis I and meiosis II.

Expert Solution & Answer

Explanation of Solution

In meiosis I, anaphase I stage includes two homologous chromosomes having centromere which is the center point of the two chromosomes. The chromosomes remain intact with the help of cohesion between them and are protected by a protein known as shugoshin. This protein acts as a protective agent.

At the end of metaphase II, the centromere protection breaks down. This breaking down of shugoshin protection on the centromere allows the sister chromatids to separate in anaphase II.

Conclusion

The shugoshin, a protective protein does not allow the chromatids to separate in anaphase I but in anaphase II, the degradation of protective protein allows the two chromatids to separate.
