The human body is made up of billions of cells. These cells grow and divide through a process called cell division. There are two types of cell division: mitosis and meiosis. Mitosis is a type of cell ...

In a closer examination of how D. pachys reproduces, the research team found that, like many other asexual organisms, the process of making germ cells -- sperm or ova -- had been modified to prevent ...
