Cell Reproduction Overview

In this post, we are going to compare and contrast the different ways cells reproduce, such as meiosis, mitosis, and cloning.

Meiosis: Meiosis is the division of one cell that results in four daughter cells. Each cell has half the number of chromosomes from the parent cell. This process is similar to mitosis in the fact that in the first stages the DNA is copied, however, where mitosis would normally align with spindles, meiosis cells align and contract chromosomes from the opposite DNA copy. These then split into two cells, and then undergo the same type of process to split into the resulting four daughter cells.

Mitosis: Mitosis is the division of one cell that results in two daughter cells with the exact number and kind of chromosomes as the parent cell. The parent cell makes one copy of its chromosomes and then divides itself, forming two distinct cells with nuclei.


Cloning: In this type of cell reproduction, the original DNA is manually emptied from the parent cell and replaced with the DNA from the cell you wish to clone. This will result in a cloned cell.
