what is the method of reproduction in C. elegans?
Homework Answers
Caenorhabditis elegans is a nematode. It is a non pathogenic organism surviving in decaying organic matter. It feeds on bacteria. The male worms have single lobed gonad, a vas deferens and a tail containing spicule. The hermaphradite worm contain two ovaries, oviducts and single uterus.
When environmental conditions are favourable, hatched C.elegans larvae develop through four stages designated as L1 to L4. Hermaphrodites produce all their sperm in the L4 stage and then produce only oocytes. The sperm cells are stored in the same area of the gonad as the oocytes. The fertilisation takes place in spermatheca. Sometimes, the male worms can also inseminate the hermaphrodite worm.

Give five in depth, detailed reasons why C. elegans is included in the list of model organisms used widely in research and in developmental biology. In each of your answers describe a trait of the organism and how that is useful in research. At least one of these answers should be unique to C. elegans.

1 pt What is an advantage of sexual reproduction over asexual reproduction? Sexual reproduction reduces genetic diversity Sexual reproduction avoids the transmission of harmful alleles to offspring Sexual reproduction allows for the undiluted, pure transmission of successful traits from one generation to the next Sexual reproduction increases the chance that a parent will transmit all their genes to an offspring

A client of yours wants to find out the best microbial environment for C. elegans. In previous meetings, the client told you that C. elegans feed on bacteria but may also be killed by certain bacteria. Therefore, it is important to figure out what bacteria are beneficial to C. elegans. In particular, the client was interested in studying the association between the density of Gluconobacter and the density of C. elegans. The client had collected some pilot data for this...

Response Questions Part A To B The roundworm Caenorhabditis elegans is a widelystudied animal model, in part because ofits small number of neurons and easilymanipulated genome. Nociception is the neural perception of an actually or potentially harmful stimulus. In C. elegans, it evokes a self-preserving withdrawal behavior. However, repeated stimulation can result in reduced withdrawal response, or habituation. Researchers compared the withdrawal response to disturbing light stimuli in wild-type C. elegansand a mutant C. elegans line that exhibits a slower...
