Meiosis 1 and 2
InterphaseDiploid cell
Prophase IChromosomes condensing
Prophase ISpindle fibres start to form
Prophase ISpindle fibres start to form, chromosomes fully condensed
Prophase IThe chromosomes are crossing over, and exchanging DNA
Prophase IThe nuclear envelope dissolves,
Prophase IThe chromosomes are ready, with a bit of each other’s dna
Prophase IThe chromosomes are ready, with a bit of each other’s dna
Metaphase IThe chromosomes are ready, with a bit of each
other’s DNA. The spindle fibres are ready to attach
Metaphase I
Metaphase IThe spindle fibres have attached to the chromosomes and the
centromeres are about to cleave.
Anaphase Ithe chromosomes have split and are pulling to each end
Anaphase 1, the chromosomes have moved to each end, Cytokinesis is
beggining
Anaphase I is almost over and Cytokinesis is almost done
Telophase I, the nuclear envelope reforms, and the chromosomes start dissolving.
Telophase I, the nuclear envelope is complete, the chromosomes will dissolve soon
Telophase I, the nuclear envelope is complete, the chromosomes will dissolve soon
Telophase I, the nuclear envelope is complete, the chromosomes will dissolve soon. The Chromosomes will build their sister
chromatids, and the cell will prepare to split
Interkenesis, the cells rest, and produces proteins.

Prophase IIthe nuclear membrane dissolves again, but there is no sharing of
dna this time
Prophase IIthe nuclear membrane dissolves again, but there is no sharing of
dna this time
Metaphase II, the chromosomes have aligned themselves.
Metaphase II, the chromosomes are aligned
Metaphase II, but the lower cell is going through Anaphase II, the chromosomes are moving to each end of the cell
Anaphase II, the chromosomes are moving to each end of the cell
Anaphase II, the chromosomes are moving to each end of the cell
Anaphase II, with cytokinesis beginning
Telophase II, the cell’s nuclear membrane is reforming, and the chromosomes are dissolving
Cytokinesis and Telophase II complete, 4 haploid cells are now ready.
