in meiotic cell division the chromosomes are not aligned in the middle like meta phase.
chromosomes
In the first stage, called interphase, the cell grows and copies its organelles and chromosomes. After each chromosomes is duplicated, the two copies are called chromatids.
It is during the prophase in which chromosomes first appear to be duplex structures.Each cell in a person typically has 23 pairs of chromosomes.
In the first stage, called interphase, the cell grows and copies its organelles and chromosomes. After each chromosomes is duplicated, the two copies are called chromatids.
The first division reduces the number of Chromosomes by half.

technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
It depends on what the animal or plant is. For humans, the first division results in 23 chromosomes per cell
