  • Front
  • Back
somatic cells
nonreproductive cells
meiosis I
prophase I-chromosomes pair; synapsis and crossing over occur
metaphase I- paired homologous chromosomes align on metaphase plate
anaphase, telephase I-chromosomes seperate;sister chromatids remain together
Meiosis II
Prophase II-new spindle forms in each cell and nuclear membran breaks down
Metaphase II -spindle apparatas is in place. Chromosomes consisting of sister chromatids joined at centromere align along the metaphase plate. Kinetochore microtubules from opposite poles attach to opposite sides of same centromere
Anaphase II-microtubles shorten and centromeres split. Sister chromatids are pulled to opposite poles
Telophase II-nuclear membranes reform. around four different clusters of chromosomes. Four haploid cells result.
Independant assortment
resutls from meiosis I
parthenogenesis
common form of reporoduction in arthropods. fertilized eggs develop into females. Unfertilized form into males.
