Meiosis and Chromosome Number

What stage of Meiosis is being shown and described:

Cell divides into 2 daughter cells. (2n...Diploid cells)

• Prophase 1

• Metaphase 1

• Anaphase 1

• Telophase 1

What stage of Meiosis is being shown and described: Each chromosome is made up of 2 copies of a homolog/2 chromatids

• Prophase 2

• Metaphase 2

• Anaphase 2

• Telophase 2

What stage of Meiosis is being shown and described: Chromatids split forming individual chromosomes and are pulled to opposite ends of the cell.

• Prophase 2

• Metaphase 2

• Anaphase 2

• Telophase 2

What stage of Meiosis is being shown and described: Each chromosome lines up in the middle of the cell.

• Prophase 2

• Metaphase 2

• Anaphase 2

• Telophase 2

Chromosome number is halved in daughter cells.
