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. Before performing this experiment we hypothesized that we would be able to see that crossing over did indeed occur in the S. fimicola. We tested our hypothesis by growing our own culture and observing it under a

Genetic Variation in Sordaria Finicola Introduction: The purpose of the Sordaria Lab was to explore the affects of genetic variation caused by meiosis and to record how sexual reproduction] affects the amount of crossing over in certain strains of Sordaria Fimicola. These organisms are ascomycetes and are also known as sac fungi. This is because the shape of their asci is in the form of a sac; inside each sac there are structures called ascospores. It is these structures‚ ascospores‚ where genetic

Sordaria fimicola and Genetic Diversity 23 October 2013 Sordaria fimicola and Crossover Frequencies in relation to Evolution Canyon Introduction Evolution Canyon is an important natural phenomenon‚ which is widely studied for its benefit in helping recreate evolution in a short period of time. It helps us visualize evolution‚ a process that takes place in the span of millions of years‚ because the animals on the canyon go through “evolution” in a very short‚ examinable time. There are two types

Nicole Hain Bio 110 Sordaria fimicola Lab Report Introduction “Evolution Canyon” consists of two slopes in Israel that are close in proximity‚ but have a huge difference in environment. This makes the slopes a good model system for exploring evolution‚ especially because they’re so close to one another. The South Facing Side (SFS) receives more sunlight than the North Facing Side (NFS). This extreme sun exposure causes the South slope to have drought and arid conditions whereas the North side has

Are you looking for a fun experiment that you can perform for a psychology class? This experiment on gender and memory is relatively quick and easy to perform‚ which is a bonus if you are short on time and resources. Could gender differences play a role in short-term memory? We often hear women complain that their husbands can’t remember important dates like anniversaries or birthdays‚ but could this phenomenon be due to something like memory differences between men and women. Some previous research
