C. Elegans Lab Report

Genetics Lab Report We gathered tout ensemble of the materials unitedly which consisted of: a microscope, teeny worm picks to pick-up the worms, petri-dishes of C. elegans worms, 2 cleanse petri-dishes with no worms and a circle of worm food, ethanol, and a fervidness. In the following experiments I hoped to learn what types of c. elegans herm mutations were dominant or recessive by crossing mutations and befalling the F1 and F2 offspring. I excessively insufficiency to learn how the breeding of these worms will affect the genotypes and phenotypes of the offspring. assemblage all the materials to the groups workspace, we took the petri dishes full of the worms and placed them abutting to the microscope. The jump petri dish we placed nether the microscope at 37x was the bingle containing wild-type hermaphroditic offspring. The Next crosses that we experimented with were wild-type males with sma-9 hermaphrodites. Taking the worm-pick, and putting it in the flame en sured that it was barren to use in the petri dish with the worms. Then, using that nib under the microscope, we picked out some worms that were in the L4 stage of information (shown in Diagram 1), both hermaphrodites and wild-type males and placed them in a altogether new petri dish to determine offspring.

They were quite small and were much(prenominal) a high number of them in the prepared petri dishes, to a greater extent or less 500 in each. It was difficult to find the males in the dishes because they barely consisted of 5% or less of the population. The males were as well somewhat ruffianly to di fferentiate from the hermaphrodites. The d! ifference is shown to a disgrace place in the take in below: In picture A, the picture shows a male worm, shown by the flat track. The gynandromorph is in picture B where the tail is open and close to wispy. It was extremely difficult to pick the worms up with the tools that we had in the firstly lab. It seemed to just poke into the jelly-like material that the worms were on/in. Also, when picking up the worms it was often hard to tell how many...If you necessitate to get a full essay, order it on our website: BestEssayCheap.com
