Ceanorhabditis elegans is a powerful tool to help understand how organisms develop from a single cell into a vast interconnected array of functioning tissues. Early work in C. elegans traced the complete cell lineage and structure at the electron microscopy level, allowing researchers unprecedented insight into the connection between genes, development and disease. Appreciating the stereotyped development and reproductive program of C. elegans is essential to using this model organism to its...

The easiness of maintaining and propagating the nematode C. elegans make it a nice model organism to work with. The possibility of synchronizing worms allows the work with a significant amount of subjects at the same developmental stage, what facilitates the study of one particular process in many animals.

Saccharomyces cerevisiae is a species of yeast that is an extremely valuable model organism. Importantly, S. cerevisiae is a unicellular eukaryote that undergoes many of the same biological processes as humans. This video provides an introduction to the yeast cell cycle, and explains how S. cerevisiae reproduces both asexually and sexually Yeast reproduce asexually through a process known as budding. In contrast, yeast sometimes participate in sexual reproduction, which is important because...

Ceanorhabditis elegans has been, and is still, used to great success as a model organism for studying a variety of developmental, genetic, molecular and even physical phenomena. In order to use C. elegans to its full potential, proper care and attention to the basic maintenance of this powerful organism is essential. In this video you will learn the basic housing and feeding requirements of C. elegans, how to correctly handle and manipulate worms using a worm pick and how to freeze and recover...
FAQs
During larval development, a hermaphrodite first produces sperm and later switches to producing oocytes. This temporal separation supplies the gametes needed for self-fertilization while preserving a defined reproductive sequence. Studying the switch lets researchers examine gametogenesis, the formation of sperm and oocytes, and how reproductive cell production is organized over development.
Fertilization occurs internally when an oocyte encounters sperm stored by the hermaphrodite. This arrangement allows sperm produced earlier to participate in later fertilization rather than requiring immediate mating. It also makes the relationship between gamete production, storage, and fertilization accessible for studies of fertility and reproductive mechanisms.
Males alter the genetic context of reproduction by mating with hermaphrodites instead of relying only on self-fertilization. Their participation can increase genetic diversity, allowing comparisons between self-fertilized and mated reproduction. This distinction is useful when investigating inheritance, sex determination, and how reproductive mode influences biological experiments.
A basic reproductive sequence can be followed from gamete production through fertilization, embryo laying, and larval development. Researchers can therefore relate an observed outcome to a defined stage, from the production of sperm or oocytes to progression through larval stages and adulthood. This staged sequence supports controlled developmental analysis.
Researchers use C. elegans reproduction to investigate meiosis, gametogenesis, sex determination, gene function, and reproductive aging. The system connects cellular events in reproductive cells with organism-level outcomes such as fertility and development. Its short generation time and tractable genetics support controlled experiments across these areas of biology.
In biology, this model links inheritance and development within one experimentally tractable reproductive system. Self-fertile hermaphrodites provide one route for examining reproductive processes, whereas males provide a route for increased genetic diversity. Comparing these contexts helps researchers study how reproduction relates to gene transmission, fertility, and developmental progression.
