Reshmi Radhakrishnan‚ TA: Jared Tues Rm 24 Experiment 6 Purpose: To analyze if diploid yeast strain heterozygous for ARG8 ADE2 HIS3/arg8 ade2 his3 on chromosome XV and TRP1/trp1 on chromosome IV irradiated with UV light underwent mitotic recombination to form homozygous recessive ade2/ade2 mutants. The ade2/ade2 mutant are selected then plated on different media to observe if the homozygous recessive mutants were due to mitotic recombination. Controls: If all the red cells grew on the CSM-Trp

Genetic Drift Worms Lab 1. The average number of generations it took for the smaller population to become fixed was 10.2. 2. The average number of generations it took for the larger population to become fixed was 10.9. 3. In the smaller population I started off with six variations of the worm and ended with one variation. In the larger population I started off with 12 variations of the worm and ended with 1. 4. Genetic drift caused the changes in these populations. 6. Genetic drift has a

Christian Chou Mrs. McCarron 12/10/14 A.P Biology Drosophila melanogaster Genetics Introduction: The common fruit fly‚ scientifically named Drosophila melanogaster‚ is used by many in genetic studies. Because they can be easily cultured‚ have a relatively short generation time‚ and are prolific breeders‚ fruit flies are often very popular in genetic investigations. Furthermore‚ mutations and sex are easy to visualize among the fruit flies. Male fruit flies have a smaller abdomen than their female counterparts

In Lab 8‚ we had analyzed remains found at a wooded area near Jonesburg and tried to determine if the bones belonged to a 28-year-old woman who had been reported missing from a city within the vicinity. Upon analysis‚ it was determined that they did belong to a female. However‚ it was not possible to determine if the bones did belong to the missing women. Lab 12 presented the opportunity to genetically analyze the remains found. DNA profiling‚ also referred to as typing and fingerprinting‚ uses genetic

Genetic Observations Through The Studies of Hybrid Corn‚ Single Gene Human Traits‚ and Fruit Flies The basic foundation of modern genetics was led by Gregor Mendel (Corcos‚ 1993). Mendel was not the first to experiment with heredity‚ and our Lyman Briggs biology class will not be the last to deal with genetics. Genetics is the science of heredity. In our lab‚ we had three main objectives. First‚ we evaluated our data on monohybrid and dihybrid corn cross seed counts against Mendel ’s theoretical

Abstract Population genetics is the study of how localized groups of individuals capable of interbreeding and creating fertile progeny change genetically over time. The Hardy-Weinberg equilibrium accounts for gene pools that do not change genetically over time. In this experiment‚ I intended to determine whether the sample population consisting of my fellow biology lab classmates would fall in the Hardy-Weinberg equilibrium with respect to the ALU insert from human chromosome 8. My hypothesis was

Fruit Fly Genetics Lab Kelly Hernandez 5/31/14 Drosophila melanogaster is a small‚ common fly found near unripe and rotted fruit. It has been in use for over a century to study genetics. Thomas Hunt Morgan was the best biologist studying Drosophila early in the 1900’s. Morgan was the first to discover sex-linkage and genetic recombination‚ which placed the small fly in the forefront of genetic research. Scientists have used Drosophila for many reasons. For one they are very easy to maintain‚

Research Question “Evaluation of the commercialization of Bt-Corn breeds: how it is both economically efficient and overall beneficial for the environment.” Abstract This paper discusses and evaluates both the negative and positive aspects and raised controversial issues regarding Bt-Corn‚ a transgenic maize developed through genetic engineering and biotechnology methods‚ and will finally conclude that the commercialization of Bt-Corn breeds for the past 14 years have been both economically advantageous

Transport of vesicles facilitated by kinesin and the effects of mutations in nerve transmission in Caenorhabditis elegans Introduction A nerve cell is made up of three main structures: the soma‚ the axon and the synapse. When a nerve cell receives a signal‚ a protein called kinesin travels anterograde along the axon and guides the synaptic vesicles until it reaches the synapse. This triggers the release of the neurotransmitters stored within the vesicles. Once released‚ the neurotransmitters then

FRUIT FLY PURPOSE: The purpose of this lab is to determine what genetics are dominant and which one is recession in the fruit fly and to see what genetics are past down from generation to generation.
