For a class of 30 students culture the 3 sordaria strains and then set up cross plates of wild type x mutant tan and wild type x mutant gray the gene to centromere distance for tan and gray genes can then be calculated. Mapping genes in sordaria during the laboratory period when the sordaria cultures have matured, you will observe the asci under the compound microscope obtain a microscope slide place one drop of water in the center of the microscope slide. In a very similar laboratory experiment, meiosis and recombination in sordaria fimicola, the same approaches of the two labs shared common procedures including: crossing a wild type and mutant type gene, growing the hyphae in rotting vegetation, and calculating the genetic map distances.

The sfs receives multiple times the uv radiation from the sun that the nfs receives, has fluctuating weather, and is generally an arid and less hospitable region compared to the temperate, stable environment of the nfs scientists collected wild type sordaria fimicola inhabiting both slopes and discovered that the strains from the sfs exhibited higher [. In another lab project i am considering for the fall class, i have been experimenting with crossing sordaria fimicola fungi these are molds in the huge phylum of ascomycete fungi that have spores in filaments (), which are ordered meiotic products so it is an excellent example of meiosis and genetic recombination--if you can get it to work. Sordaria fimicola is an ascomycete fungus that can be used to demonstrate the results of crossing over during meiosis sordaria is a haploid organism for most of its life cycle.

Where he is coordinator of the introductory biology laboratory course for biology majors he received his bs in biology (1967) and ph d in behavioral ecology (1971) from we selected the genus sordaria over neurospora for this study because of the absence of asexual, in sordaria fimicola (figure 11),.

Sordaria lab effects of crossing over in sordaria fimicola abstract sexual reproduction in organisms is a cause for genetic variation this can be seen through the process of meiosis in sordaria fimicola because of the effects of crossing over and independent assortment that occur in meiosis i. Sordaria can be used as a model to study meiotic segregation the trait followed was the ascospore color ascospore color is a single gene trait therefore it is easily observed under a light microspore.

Sordaria fimicola is a species of microscopic fungus it is commonly found in the feces of herbivores sordaria fimicola is often used in introductory biology and mycology labs because it is easy to grow on nutrient agar in dish cultures. Understanding sordaria while i have done the sordaria lab for many years, i don’t think that i really understood it until 2017here goes sordaria fimicola is a fungus with a lifestyle that gives us a window into meiosis and crossing over. Introduction sordaria fimicola is a fungi that is a part of the ascomycota phylum and is a model organism organisms in this phylum have a reproductive characteristic called an ascus and the parethecium ( a sac-like cell containing 4 to 8 haploid spores ) contains the ascus these spores are produced by meiosis to make 4 haploid spores.
