anaphase 1 -during anaphase 1 sister chromatids remain attached at their centromeres, and homologous chromosomes move to opposite poles.

Meiosis 2 typically produces _____ cells, each of which is _____.

four.....haploid -At the end of meiosis 2 there are typically 4 haploid cells

During _____ chromosomes align single file along the equator of a haploid cell.

metaphase 2 -Metaphase 2 is essentailly the same as mitotic metaphase except that the cell is haploid.

prophase 1 -Synapsis, the pairing of homologous chromosomes, occurs during phophase 1

During _____ a spindle forms in a haploid cell.

prophase 2 -prophase 2 is essentially the same as mitotic prophase except that the cells are haploid
