Difference between Anaphase,Anaphase 1 and Anaphase 2 ?

Dear student,
Please find below the solution to the asked query

Option 1 would be correct.
This happens in Meiosis 1 .
 

Anaphase of mitosis

Anaphase I of meiosis

Anaphase II of meiosis

During anaphase of mitosis, the sister chromatids are pulled apart by the spindle fibres, such that each of them act as a separate chromosome. So, the chromosome number is doubled during anaphase of mitosis.

During anaphase I, the homologous chromosomes are pulled apart. The chromosome number is not doubled, but halved during this process.  Hence, in anaphase I , the chromosomes of each bivalent pair separate, while the sister chromatids remain together.

It is similar to the anaphase of mitosis. In this phase, the centromere divides and two chromatids of each chromosome are pulled apart towards the poles.

Hope this information will clear your doubts about the difference between Anaphase, Anaphase 1 and Anaphase 2 .
