Answer 11

That is one of the reasons they are used as a test organism. Very cheap to keep around, no one really cares what you do to them, the have very short generation times and in a laboratory setting have consistent fecundity, and have a relatively small genome. The nematode C. elegans has the cell destiny of every cell from from the blastula (maybe earlier, cannot remember) to adult hood. Course it only has ~1050 cells as an adult.
