Caenorhabditis elegans is a 1-mm-long soil-dwelling nematode selected by Sydney Brenner in 1965 to study animal behavior and development (particularly neural development). 1 Caenorhabditis elegans have become a popular model organism because of their rapid lifecycle, large number of progeny, and ease of cultivation in a laboratory setting. C. elegans was the first multicellular organism to have its whole genome mapped by the end of 1980. C. elegans has two sexes: male (XO) and hermaphrodite females (XX). These hermaphrodite worms have both male and female sex organs (ovatestis). Fertilization takes place internally. Why C. elegans is considered to be a good model organism?
