Meiosis Model

The model shown in this essay is a representation of meiosis one and meiosis two. The guided question I answered was how does the process of meiosis reduce the number of chromosomes in a reproductive cell? It is important for scientists to answer this question because they need to learn how a reduction in chromosomes is very critical. Without it the two gametes during fertilization, the offspring would result in with two times the regular number of chromosomes.

Scientist use models to demonstrate mitosis one, mitosis two, meiosis one, and meiosis two. A model is a three-dimensional representation of a person or a thing. Models help scientist to understand and explain certain concepts or processes. When explaining the process meiosis, it …show more content…
Meiosis one and meiosis two. Before meiosis one starts the cell is in the process of interphase. Once interphase is complete the first step in meiosis one is prophase 1. This is the phase where the chromosomes overlap and pair up with each other. This is shown below in the second picture. The next process is metaphase 1. This is the process where the chromosomes line up on the metaphase plate in a straight line and the spindle fibers start to attach to the chromosomes. This is shown below in the third picture. The next phase in anaphase. In anaphase 1, each chromosome from the pair goes to opposite ends of the cell and are pulled apart. This is shown in picture number 4. The next phase is telophase 1. The next phase is telophase/cytokinesis. This is when the two chromosomes split the cell into two cells. These two new cells are called daughter cells. This is shown in picture 5. After all of these processes are complete its time to start meiosis 2. Meiosis 2 is the second of the two consecutive divisions of the nucleus of a eukaryotic cell during meiosis. Meiosis 2 turns the new daughter cells into granddaughter cells. The daughter cells go through prophase 2, metaphase 2, anaphase 2, telophase 2, and
