Question

Name the stage of cell cycle at which one of the following events occur:
(i) Chromosomes are moved to spindle equator.
(ii) Centromere splits and chromatids separate.
(iii) Pairing between homologous chromosomes takes place.
(iv) Crossing over between homologous chromosomes takes place.

Answer 1

 (i) Metaphase

(ii) Anaphase

(iii) Zygotene of meiosis I

(iv) Pachytene of meiosis 


i hope it's helpful to you

Answer 2

(i)Chromosomes are moved to spindle equator _Metaphase. It is a stage of mitosis in the eukaryotiuc cells.

(ii) Centromere splits and chromatids separate- Anaphase. it is a stsge of  mitosis after the process of metaphase.  

(iii) Pairing between homologous chromosomes takes place -Zygotene of Meiosis I

(iv) Crossing over between homologous chromosomes takes place- Pachytene of Meiosis I.
