Differences between meiosis I and meiosis II include:

a. how the chromosomes line up at the equator of the cell during meiosis I or meiosis II.

b. the pairing of chromosomes in meiosis I but not meiosis II.

c. the amount of DNA in a cell at the end of meiosis I or meiosis II.

d. all of the above

Meiosis I Prophase I - Synapsis occurs (each pair of chromatids joins its homologous pair and forms a tetrad) (group of 4 chromatids); Recombination occurs ("crossing over", pieces of tetrad twist around and exchange segments Metaphase I - Tetrads line up along the equator of the cell Anaphase I - Non-disjunction occurs - chromosome pairs separate Telophase I - cells divide and 2 haploid daughter cells are formed

Meiosis II Prophase II - Chromosomes move toward the middle of the cell Metaphase II - Chromosomes line up at the equator Anaphase II - Chromosomes separate into chromatids Telophase II - both daughter cells divide and 4 haplod cells are formed
