Meiosis

Meiosis I

The first division separates the homologous chromosomes into two intermediate cells

Interphase

Chromosomes are not visible; DNA is dividing

Prophase I

Homologues pair up, with replicated chromosomes appearing as two sister chromatids. Homologous chromosomes pair up; crossing over may occur.

Metaphase I

Independent assortment occurs as homologous pairs line up in the middle of the cell independently of each other.

Anaphase I

Homologous pairs separate

Telophase I

2 nuclei form, the cells begin to truly separate; intermediate daughter cells form

Meiosis II

The mitotic division where the chromatids are pulled apart but the chromosome number remains the same.

Prophase II

Spindle apparatus forms. Chromosomes migrate towards the metaphase plate.

Metaphase II

Chromosomes line up on the metaphase plate.

Anaphase II

Sister chromatids (now individual chromosomes) separate.

Telophase II

Separate gametes are produced
