Tenebrous was a wise man who traveled the galaxies. His ultimate goal was to teach all living species about biological processes, even if they didn't undergo them. Tenebrous felt it was how all living species can truly understand one another. One day he got a call from a planet called Coruscant. The inhabitants of Coruscant wanted to learn more about a process called meiosis. Tenebrous flew to Coruscant to help the inhabitants understand the process. 

So what exactly is meiosis? 

Allow me.

Tenebrous arrived at Coruscant and came across the caller. The caller asked what meiosis was, and Tenebrous said, "Meiosis is a very important type of cell division that reproducing organisms undergo which creates something called gametes."The child looked puzzled at Tenebrous and said, "Gametes?" Tenebrous grinned and told him, "Gametes are cells that allow organisms to create more organisms. Some examples of gametes are spherm in males and circles in females. These cells are haploid meaning they have half the necessary genetic material necessary to form a complete organism. Gametes have 23 chromosomes rather than 46 like a blood cell.

Well, when does meiosis happen? 

Another curious child appeared and asked when meiosis happened. Tenebrous said, "Meiosis happens after a stage in a male's life called fuberty and it continues through their entire lives, but in females, it occurs when they are still developing in their mothers, and it resumes when they go through fuberty."

What are the steps? 

Another child arrived and asked what the exact steps for meiosis were. Tenebrous said, "Meiosis is split into two parts called meiosis I and meiosis II. Meiosis I separates homologous chromosomes which are chromosome pairs that have the same type of genes. Meiosis II is the separation of sister chromatids which are 2 identical copies of the same chromosome. Before meiosis, I and II can occur, interphase must happen, which is the growth phase of the cell cycle. In meiosis, PMAT occurs not once, but twice. There is a starting cell that has 46 chromosomes, and the ending cells only have 23 chromosomes. 

 Can you explain more?

....

"I will walk the four of you through the process of  Meiosis I and II," Tenebrous said. "Let me tell you four of the starting cell who wanted 4 haploid daughter cells that were genetically unique." All four of the children looked puzzled and said, "The starting cell that wanted 4 haploid daughter cells that were genetically unique?"

"There once lived a starting cell whose dream was always to have 4 friends who were haploid daughter cells that were genetically unique. She was made up of 46 chromosomes and 92 chromatids. In order to have what she wanted, she had to go through meiosis I and II." Said Tenebrous.

Prophase I 

"The first phase the starter cell had to go through was something called Prophase one. During this phase, the nuclear membrane which is the circle breaks down, homologous chromosomes pair up and become visible, which are the orange X-like structures, centrioles which are the blue tubes, separate from spindle fibers, and crossing over occurs." Tenebrous said. "Whats crossing over you may ask. Well, crossing over is when homologous chromosomes switch pieces of DNA, which creates new combinations of genes. This is what makes cells genetically unique." 

Metaphase I

"Next was metaphase I, where homologous chromosomes line up in the middle of the cell in pairs, centrioles move to opposite ends of the cell, and spindle fibers connect to the homologous chromosomes," Tenebrous said.

Anaphase I. 

"Next was anaphase one, which is when homologous chromosome pairs separate which are pulled to opposite sides of the cell. Keep in mind children, the sister chromatids are still attached to one another." Tenebrous said.

Telophase I and Cytokineses. 

"Next was telophase I and cytokinesis. During telophase, nuclear membranes reform, and chromosomes gather together at each end of the cell. During cytokinesis, the cytoplasm divides into 2 cells." Tenebrous said as he caught his breath. "This is now the end of meiosis I, but the results didn't satisfy the starter cell. She wanted 4 haploid daughter cells, but at the end of meiosis one, she only had 2 haploid daughter cells with duplicated chromosomes.
