Homologous chromosomes line up in the center of the cell
KonstantinChe [14]

Answer:

Metaphase I

Explanation:

Homologous chromosomes are paired to facilitate crossing over during prophase I of the meiosis I. This is followed by alignment of homologous chromosomes at the equator of the cell during metaphase I. The process is assisted by microtubules of spindle apparatus. The kinetochore microtubules of the spindle apparatus attach themselves to the kinetochores of chromosomes.

The two sister kinetochores of duplicated homologous chromosomes are attached to the opposite pole to align the homologous pair at the center of the cells. Metaphase I is followed by anaphase I during which homologous chromosomes move towards the opposite poles.
