Meiosis Animation

anaphase II

During anaphase II sister chromatids separate and migrate to opposite poles.

Telophase I and cytokinesis

At the end of telophase I and cytokinesis there are two haploid cells.

Anaphase I

During anaphase I homologous chromosomes, consisting of sister chromatids, migrate to opposite poles.

interphase

During interphase the centrosome duplicates and the chromosomes are not condensed.

Metaphase I

During metaphase I tetrads align along the metaphase plate.

Telophase II and cytokinesis

Four haploid cells are present at the end of telophase II and cytokinesis.

Prophase I

Homologous chromosomes pair during prophase I.

Metaphase II

Metaphase II is essentially the same as mitotic metaphase except that the cells are haploid.

prophase II.

The events of prophase II are essentially the same as those of mitotic prophase except that prophase II cells are haploid.

Homologous chromosomes migrate to opposite poles during _____.

anaphase I. During anaphase I sister chromatids remain attached at their centromeres, and homologous chromosomes move to opposite poles.

During _____ sister chromatids separate.

anaphase II . Anaphase II is essentially the same as mitotic anaphase except that the cell is haploid.
