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

2012 section 30 October 2012 Sordaria Lab Meiosis and genetic diversity in the model organism‚ Sordaria Introduction Meiosis is a process in which a cell divides to form four haploid (1N) cells. The Sordaria lab is a perfect way to see an example of how meiosis impacts the life of an organism. Meiosis can be broken down into parts that contain a few stages. These stages are similar to that in Mitosis (Prophase‚ Metaphase‚ Anaphase‚ and telaphase.) during Meiosis I‚ crossing over and independent

Introduction: Genetic Diversity: Every individual has a unique genotype. This is equal to the combination of alleles of all its genes. The greater the number of genotypes in a population‚ the greater the genetic diversity. Genetic mutations produce new alleles of

flask-fungi. The natural habitat of the three species of Sordaria that have been the principal subjects in genetic studies is the dung of herbivorous animals. The species S. fimicola is common and worldwide in distribution. The species of Sordaria are similar morphologically‚ producing black perithecia containing asci with eight dark ascospores in a linear arrangement. These species share a number of characteristics that are advantageous for genetic studies. They all have a short life cycle‚ usually

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

the topic of genetic diversity‚ it is imperative that you‚ the reader‚ can get an understanding of what all topics and points of focus that is taken into consideration when discussing genetic diversity. This includes a brief history as to how this came about‚ and what components allow this process to occur. Genetic diversity can be a complicated‚ yet interesting topic to cover. From the name of the process of genetic diversity‚ it can be inferred that this deals with genes and genetics. The first

viruses or environment factors. When a mutation occurs in ones genetic structure‚ there is often a push to find out what went wrong and if it was a onetime occurrence or a genetic abnormality that no one in the family knew about until the recent discovery. This genetic abnormality occurs when there is a dominant gene which comes from a parent. This dominant gene attaches itself to a recessive gene and sparks a change in the genetic sequence of the offspring. This is most relevant as I was observing

Unit 5 Free Response Meric Pope Meiosis 1 and Mitosis are very similar events‚ however‚ they have certain differences. One difference is crossing over. Meiosis 1 does cross over and because of that‚ it creates genetic changes. Mitosis ‚ on the other hand‚ does not cross over. Something else that is different is the way it occurs. Meiosis 1 is sexual but Mitosis is asexual. Another change is the number of divisions that each event goes through. Meiosis 1 goes through 2 divisions which ends up having
