Sister Chromatids

Identical copies of a chromosome, connected by a centromere, that are created during DNA replication and separated during cell division.

Anaphase II

A phase of meiosis II where sister chromatids are separated and moved to opposite poles of the cell, leading to the formation of four haploid daughter cells.

Metaphase II
