Homework Help: Science

Please help me with matching the stages of the meiosis to its proper description.

1. Members of each homologous pair separate from each other (chromatids) still remain together).
2. Homologous chromosomes pair up with each other and chromosomes 'cross over' by exchanging their genetic material in some places.
3. Chromosomes become bound by a nuclear membrane and two new cells are formed.
4. The nuclear membrane reforms, forming four new cells with only half the number of chromosomes as the original cell.
5. Chromosomes appear as pairs of chromatids, joined at the centromere.
6. Chromosomes consisting of two chromatids line up along the center of the cell spindle.
7. Chromatid pairs separate and one of each pair moves to opposite ends of the cells.

Meiosis Stages:
Prophase 1
Anaphase 1
Prophase 2
Anaphase 2
Metaphase 1
Telophase 1
Metaphase 2
Telophase 2

and it says:
Note that for our purposes there is little difference between Telophase 1 and Prophase 2.
