In prophase II,
dyad has two chromatids attached to a common
In metaphase II,
chromosomes move to the metaphase plate, and
centromeres start to divide.
In anaphase II,
the divided centromeres pull sister chromatids to opposite poles (
After telophase II and cytokinesis II,
cell division is complete, producing
Each haploid daughter cell is a potential
gamete and has one member of each pair of homologous chromosomes.
Note that if
disjunction fails (
nondisjunction) in either meiosis I or II,
the gametes will have abnormal numbers of chromosomes.
