Sordaria fimicola

Evolution Canyon is a particularly special place for observing how a specific species may change overtime, in two different environments. Evolution Canyon I, located in Lower Nahal Oren, Mount Carmel, has two slopes; a South Facing Slope, which receives higher solar radiation, higher temperature, and experiences droughts, and a North Facing Slope, which shows a more temperate climate, with shade and humidity engulfing its physical atmosphere (Nevo, 2009). The fungus Sordaria fimicola can be easily obtained from both of these slopes and grown in a lab, making it an ideal organism for scientists to study. It produces fruiting bodies containing asci with eight spores. These asci arrangements in the spores can than be viewed under a microscope…

of asci showing crossing over will be 56% before dividing by two in the wild type and gray Sordaria Fimicola cross due to the location of the spore color gene about halfway between the centromere and end of the chromosome. Thus, the distance between the gene and the centromere will be 28 map units. Variables • Dependent- Percent of crossover, number of asci showing crossover • Independent- Distance from gene to centromere • Control- Sordaria Fimicola culture, slide, time, strains being…

Abstract: This experiment was meant to look and find gene linkages and determine the crosses of the tan x wild type (black), gray x wild type (black), and tan x gray spores of the Sordaria fimicola. To accomplish the crossing, the plates filled with auger had to be set up with each individual kind of spore. Three plates with two different spore colors of sordaria in each. One plate was black and tan, black and gray, and gray and tan. For gene to centromere distance the standard deviation was…

The organisms used in this lab are the Ascomycota fungi Sordaria fimicola. S. fimicola is made of haploid cells in a hyphae. A diploid cell is formed when two haploid nuclei bud off of the hyphae. This diploid cell then undergoes meiosis and mitosis forming eight haploid cells called a tetrad. The cells develop within an ascospore, and a group of ascospores is an ascus. An perithecia contains the asci (Glase, 1995). S. fimicola have a unique feature in their meiotic process which easily lends…

Introduction Evolution Canyon is a canyon in Israel where the two slopes face very different conditions. The Northern Facing Slope (NFS) is lush, green, and shaded while the Southern Facing Slope (SFS) is dry and has little protection from intense sunlight. Evolution Canyon is a natural laboratory, meaning that nature has provided variations, allowing it to be a great location for experiments. Specifically, it is a great location to study natural selection and evolution. Researches from the…
