Meiosis

Meiosis!

Two different cell division stages:

Interphase:

Before meiosis begins, genetic material is duplicated.

Meiosis I

Prophase I:

The duplicated chromatin condenses and each chromosome consists of two closely associated sister chromatids.

Metaphase I:

The homologous chromosomes align(equilateral plate)

Anaphase I:

The homologous pairs separate with sister chromatids remaining together.

Telophase :

2 daughter cells are formed with each sister containing only one chromosome of the homologous pair.

Meiosis II

Gamete Formation

Prophase 2:

DNA does not replicate

Metaphase 2:

chromosomes align at equilateral plate

Anaphase 2: Centromeres divide & sister chromatids move separately to each opposite pole.

Telophase 2:
