1
Q
Meiosis
A
I.P.M.A.T.P.M.A.T
2
Q
Prophase 1
A
Pair up
Homologous chromosomes pair up and crossing over occurs
3
Q
Metaphase 1
A
Meet
Homologous pairs line up at the equator of the cell.
4
Q
Anaphase 1
A
apart
Homologous chromosomes separate
5
Q
Telophase 1
A
two nuclei
nuclear membrane reforms & cell begins to divide
6
Q
Prophase 2
A
produce
new spindle fibres are formed
7
Q
metaphase 2
A
middle
chromosones (2 chromatids) line up on the metaphase plate
8
Q
Anaphase 2
A
appart
centromeres divide, chromatids move to opposite poles of cell
9
Q
Telophase 2
A
nuclear envelope reforms, chromosomes return to interphase state, cytokenesis occurs, 4 non-identical daughter cells
