Centromeres of replicated chromosomes line up along the cells equator.
Sister chromatids separate and move toward opposite poles of the cell.
Paired homologous chromosomes line up along the cells equator.
Homologous chromosomes separate and move toward opposite poles.
Metaphase I only
Anaphase I only
Metaphase I and II only
Anaphase I and II only
There are 2 divisions.
Homologous chromosomes pair up during Prophase I.
Anaphase I separates homologous chromosomes & Anaphase II separates sister chromatids.
Interphase (DNA replication) occurs twice.
