Question

what is the purpose of ”Caenorhabditis elegans genetic: monohybrid and dihybrid crosses” and ”worm picking” experiment?

Answer 1

In "Caenorhabditis elegans genetic:monohybrid and dihybrid crosses" experiments, the goal will be to deduce unknown parental genotypes by analyzing the phenotypes of their “children” and “grandchildren”.

Purpose of "Worm picking" experiment:

Caenorhabditis elegans is a small, free-living soil nematode that is commonly found in many parts of the world. For use in laboratory settings, the worms are typically grown on agar media plates spread with E. coli . The worms are only about 1 mm long as adults, so it is easy to grow millions of worms in a small amount of lab space. Because of their size, worms are handled by viewing them under a dissecting microscope, and

individual worms are transferred from one plate to another using a worm “pick” (a small hand-made platinum microspatula).This is a very valuable tool

that you will use to move worms from place to place. A standard “worm pick” is a short length of platinum wire fashioned into a microspatula and melted into a

glass pasteur pipet. And then observation is done using microscope to identify sex of that nematode.
