Name the stage of the cell cycle at which the following events occur:
$(i)$ Chromosomes are moved to the spindle equator
$(ii)$ Centromere splits and chromatids separate
$(iii)$ Pairing between homologous chromosomes takes place
$(iv)$ Crossing over between homologous chromosomes takes place
$(i)$ Chromosomes are moved to the spindle equator
$(ii)$ Centromere splits and chromatids separate
$(iii)$ Pairing between homologous chromosomes takes place
$(iv)$ Crossing over between homologous chromosomes takes place
(N/A) $(i)$ Metaphase: Chromosomes align at the equatorial plate.
$(ii)$ Anaphase: The centromere of each chromosome splits,allowing sister chromatids to separate and move toward opposite poles.
$(iii)$ Zygotene of meiosis $I$: Homologous chromosomes undergo pairing,a process known as synapsis.
$(iv)$ Pachytene of meiosis $I$: Crossing over occurs between non-sister chromatids of homologous chromosomes.
$(ii)$ Anaphase: The centromere of each chromosome splits,allowing sister chromatids to separate and move toward opposite poles.
$(iii)$ Zygotene of meiosis $I$: Homologous chromosomes undergo pairing,a process known as synapsis.
$(iv)$ Pachytene of meiosis $I$: Crossing over occurs between non-sister chromatids of homologous chromosomes.
