what happens to chromosomes during anaphase
Anaphase
The separation of sister chromatids marks the beginning of anaphase in mitosis or meiosis. During anaphase, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.

Anaphase. During anaphase, the sister chromatids separate and are pulled to opposite ends of the cell by the spindle fibers. This separation ensures that each daughter cell receives an identical set of chromosomes.
Chromosomes move to opposite poles of the cell.
Anaphase I of meiosis is more analogous to anaphase in mitosis than anaphase II. In anaphase I, homologous chromosomes are separated and pulled to opposite poles, similar to how sister chromatids are separated during mitotic anaphase. In contrast, anaphase II involves the separation of sister chromatids, which is akin to what occurs in mitosis but happens after a reductional division in meiosis. Thus, the mechanisms and outcomes of anaphase I align more closely with those of mitosis.
The chromosomes move apart, towards the opposite poles.
The tetrads are pulled apart.
prophase, metaphase, anaphase, telophase (including cytokinesis)
The phase you are referring to is metaphase I. In metaphase I of meiosis, homologous pairs of chromosomes line up at the cell's equator before they are separated and pulled to opposite ends of the cell during anaphase I.
