interphase
replication of DNA during the S phase. Each cell has 46 chromosomes and 92 sister chromatids
prophase I
chromosomes form and homologs synapse. crossing over occurs. spindle formation is complete. nucleolus and nuclear membrane disappear.
metaphase I
tetrads line up on the metaphase plate. independent assortment occurs.
anaphase I
homologous chromosomes separate and move towards opposite poles.
telophase I
chromosomes uncoil into chromatin. nucleolus and nuclear membrane reappear. spindle breaks down. cytokinesis begins
interkinesis
no dna replication occurs. division of cytoplasm and organelles does occur.
prophase II
chromatin coils to chromosomes. spindle forms. nucleolus and nuclear membrane disappear.
metaphase II
chromosomes are located on the metaphase plate. because of crossing over the chromosomes are not identical
anaphase II
sister chromatids separate and move to opposite poles.
telophase II and cytokinesis
chromosomes uncoil. nucleolus and nuclear membrane reform. spindle breaks down cytokinesis occurs resulting in 4 haploid cells.
