Can someone explain Meiosis 1 and II to me like I'm a baby? (i really don't understand it!) 15 pts

topjm [15]

Answer:

Meiosis 1 is when the homologous chromosomes separate and crossing over occurs. Meiosis 2 is when the sister chromatids seperate and produces 4 haploid daughter cells.

Explanation:

The phases of Meiosis 1 are, Interphase, Prophase 1, Metaphase 1, Anaphase 1, Telophase 1 & Cytokinesis.

Interphase: DNA is replicated and organic material is synthesized.

Prophase 1: Chromosomes pair up

Metaphase 1: Crossing Over occurs and chromosomes line up at the equator.

Anaphase 1: Chromosomes pull apart

Telophase 1 & Cytokinesis: Cell pinches to both sides and begins to pull apart as the cytoplasm is copied.

The phases of Meiosis 2 are, Prophase 2, Metaphase 2, Anaphase 2, Telophase 2 & Cytokinesis.

Prophase 2: Two daughter cells are formed

Metaphase 2: Chromosomes line up at equator of both cells.

Anaphase 2: Sister chromatids are pulled apart in each cell.

Telophase 2 & Cytokinesis: The cells pinch to both sides as the cytoplasm is replicated and four granddaughter cells are formed.
