‘You won this farm on the flip of a coin’ Dibs and Girlie flip of the coin ultimately destroys their families discuss: Inheritance is a play written by playwright Hannie Rayson. The complex play consists of two families being torn apart because of a fight over a farm ownership. The toss of a coin decides the future for twin sisters Dibs and Girlie Myrtle. Four years pass since their father’s death and one must return to Mallee from Melbourne to run the farm. Both girls seem reluctant to take on

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‚

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

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

Mendelian inheritance Mendelian inheritance (or Mendelian genetics or Mendelism or Monogenetic inheritance) is a scientific theory of how hereditary characteristics are passed from parent organisms to their offspring; it underlies much of genetics. This theoretical framework was initially derived from the work of Gregor Johann Mendel published in 1865 and 1866 which was re-discovered in 1900; it was initially very controversial. When Mendel’s theories were integrated with the chromosome theory of

Alhamdulillah‚ Biology course work was completed with inspiration‚ grace and guidance that has given him. Peace and blessings be upon our Prophet Muhammad and on his family‚ then his companions and predecessors‚ the religious scholars and to all the servants of God who followed in their footsteps. Thank you very sincere gratitude to my parents who have educated

Chapter 9: Patterns of Inheritance What pattern will inheritance follow? Why is it important? Always follow patterns? Rule of Probability In tossing a coin the odds of either a head or tail is always 50%. The outcome is unaffected by the previous attempt. If 2 coins are tossed‚ each will be dependent of the other HH‚ HT‚ TH‚ TT (Probability is 25% or ¼) The rules also hold true for genetics due to the law of independent assortment. Each alternative type of outcome in a gene acts independently
