Interephase and Meiosis I

Meoisis II Separates sister chromatids

Telophase II & cytokinesis

Cytokinesis forms four haploid daughter cells (two Shown)

Anaphase II

Centromeres separate, Sister chromatids move to poles

Metaphase II

* Chromosomes arrange on metaphase II plate

Prophase II

* Nuclear envelope breaks down, centrosomes move to poles, spindle microtubules form & attach to both sides centromeres, chromosomes move towards meta-phase II plate.

Interphase

Telephase I & Cytokinesis I

* Nuclear envelope may re-form * Cylokinesus forms two haploid daughter cells * Sister chromatids remain attached

Anaphase I

homologous chromosomes move to poles

Metaphase I

Tetrads arrange on Metaphase I plate

Prohase I

* Chromosomes condense, form tetrads * synapsis non-sister chromatids cross-over * nuclear envelope breaks down, centrones move to poles, spindle microtubules form & attach to one side centromeres, tetrads move towards metaphase I plate.Subtopic

Meiosis I Separate homologous chromosomes

Centromeres chromosomes replicate
