Leptonema(1)
chromosomes begin to condense as meiosis begins
Zygonema(2)
Homologous chromosomes pair up, centrioles begin moving, haploid number of bivalents
Pachynema(3)
double structure of homologs becomes visible, tetrads
Diplonema(4)
chiasmata are visible(points of crossing over to exchange genetic information between non sister chromatids but still homologous chromosomes(one from each parent))
Diakinesis(5)
tetrads moved to equatorial plane by spindle fibers, terminalization where ciasmata move to ends of chromosomes
