The cell is in METAPHASE PHASE OF MEIOSIS. At this phase, the pairs of homologous chromosomes moves to the cell equator. These pairs of homologous chromosomes will be separated in anaphase I. The number of chromosomes remains constant until the first cell division is completed, then the chromosomes will be divided into two daughter cells.
