Stages+of+Meiosis

=Stages of Meiosis=

Meiosis I
During Meiosis I, chromosomes divert from a healthy diploid cell, and produce four haploid cells. During this process genetic diversity is created.

Phases of Meiosis I and II
There are five main steps of Meiosis I and II, other then that in Meiosis II, S phase is skipped.

Prophase I
Start of Meiosis I and II, homologous chromosomes pair. These pairs are called bivalents. Each bivalent has two chromosomes and four chromatids, with one chromosome coming from each parent cell. In this step is when the crossing over happens, crossing over is when the homologous chromosomes swap places with each other.

Metaphase I
Combination of two chromosomes align at the equator. There is a 50/50 chance for daughter cells to get either mother or father homologue.

Anaphase I
Chromosomes separate to separate polls, to form two haploid daughter cells.

Telophase I
Nuclear envelopes may form once more, or cell may begin meiosis II

Cytokinesis
Final step when two complete daughter cells form. =Vocabulary=
