Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. That means that they will never be a copy of their parents because of their different genetic material. Characteristics, such as eye color, hair type and color, the shapes of facial features, and height and build, and attribute the combinations of these to the portions of DNA inherited from each parent which makes them different but still carry the DNA of their parents.

Answer:
Atoms 
Explanation:
Atom is the most basic unit of matter. Atoms are used to describe pieces of matter, but a different kind of atom makes up an element.  A combination of atom of different elements creates a molecule. Let's say you have some water, the chemical formula is "H20." If you wanted to separate H and O, that gives you two atoms. H would be Hydrogen and the other atom is Oxygen. So when we combine these two atom they formed as the chemical formula H20.
