What stage of Meiosis is this?

Telophase I

Interphase

Chromosomes replicate, Chromatin condenses.

Prophase I

Pairing of homologous chromosomes (each chromosome consists of two chromatids), crossing over nuclear envelope breaks down, spindles form.

Metaphase I

Chromosome centromeres attach to spindle fibers, homologous chromosomes line up at the equator.

Anaphase I

Homologous chromosomes seperate and move to opposite poles of the cell.

Telophase I

The spindles break down, chromosomes uncoil and form two nuclei, the cell divides.

Prophase II

Chromosomes condense, Spidles form in each new cell, spindle fibers attach to chromosomes.

Metaphase II

Centromeres of chromosomes line up randomly at the equator of each cell.

Anaphase II

Centromeres split, sister chromatids separate and move to opposite poles.

Telophase II

Four nuclei form around chromosomes, spindles break down, cells divide.

Products

Four cells have formed, each nucleus contains a haploid number of chromosomes.
