Meiosis: reduction division. results in haploid gametes.
Haploid (n): single set of chromosomesDiploid: (2n): double set of chromosomes
Prophase I
synapsis of homologous chromosomes
crossing over occurs: exchange of genes
tetrads move to the equator
Anaphase I
homologous chromosomes separate
Telophase I
cytoplasm divides to form 2 haploid daughter cells. sister chromatids are still joined.
Meiosis II: sister chromatids separate
Prophase II
new spindle fibers form
chromosomes move to equator
Anaphase II
sister chromatids separate and move to poles
Telophase II
nuclei form
Result: four haploid daughter cells, genetically different from each other and parent cell.
