Sexual reproduction largely predominates in animals, however, indicating that this cost is outweighed ...
The cell pinches in half, and now there are two cells of the same organism. Bacteria, yeast, archaebacteria all "practice" asexual reproduction. Even some plants and animals utilize this method to pass on their genes when the conditions are right. Some bacteria can share parts of their DNA...
