Paired homologous chromosomes are found at the spindle equator during

Metaphase (mitosis) and metaphase I (Meiosis)

Explanation:

In a diploid organism, the chromosomes are present in pair called homologous pair which has to be distributed in the cells during the cell division cycle.

The distribution of the chromosomes in a cell is observed in four subphases: prophase, metaphase, anaphase and telophase.

The homologous chromosomes when are found in a condensed form and are present in the centre of the cell or at the equatorial plate is known as the metaphase.

In case of mitosis since the division takes place in one cycle, therefore, metaphase is the phase whereas in meiosis since the division takes place in two-cycle, therefore, metaphase I is correct as during the metaphase II the chromatids are present at the centre.
