Biology 301 12/3/2012 The Effects of Relative Fitness of Drosophila Melanogaster on Evolution Abstract This experiment was conducted to study the relative fitness of two phenotypes of the Drosophila melanogaster and how fitness can affect evolution in the population. The phenotypes were placed in two different environments‚ one in which contained a predator and another with no predator. Results of the experiment would show how the fitness of each phenotype is affected by providing a mechanism

Ethanol sensitivity in Drosophila melanogaster based on genotype Alexa Shumate Department of Biology Randolph-Macon College Ashland‚ Virginia Introduction With a better understanding of the genes and behaviors associated with ethanol sensitivity‚ there will be new treatments available for alcohol dependence. The main problem in determining what causes dependence to alcohol is whether it is an environmental factor or if it is the genes associated with ethanol

Abstract The basic principle of Mendelian inheritance was studied using the fruit fly‚ Drosophila Melanogaster. A Cinnabar Brown female was crossed with Wild Type male. The flies were mated in a jar containing a nutrient medium and then placed in an incubator. The experiment was conducted over a period of 5 weeks. Cinnabar (cn) and brown (bw) are two loci in Drosophila with recessive eye colour mutations. Mutations in cn cause a bright red eye and mutations in bw cause a brown eye. Double mutants

Natural and Sexual Selection of Vestigial and Wild Type Drosophila melanogaster Abstract In this experiment‚ vestigial flies as well as wild type flies were used to create some diversity as well as test one of our hypotheses. Our hypotheses are as follows; 1) The wild type flies will have a greater relative fitness compared to the vestigial flies based on only sexual selection. The wild type has a relative fitness of 1 since it has fully functional wings. Vestigial Winged flies are not as sexually

The Relationship between the Genotype and Phenotype of Drosophila melanogaster Eye Pigment Mariam Rahmanyar 100486882 T.A: Zahra Mortaji BIOL 2020 Results: Our TLC plate showed all colours expressed by the pteridine pigments for the wild-type Drosophila as expected (Figure 1). The sample A mutant which was a bright-red eye mutant also expressed the same pigments as our wild-type. Compared to the wild type‚ sample A pigment spots were lower intensity in colour under the UV

frustrated fruit flies Drosophila melanogaster Ankit Sharma April 8‚ 2013 BIO 534 Introduction The fruit flies Drosophila melanogaster show addiction-like behavior towards alcohol where the flies seem to be physiologically dependent on (Atkinson et. al.‚ 2012). The flies can thus exhibit a cognitive dependence where such behavior is stored in memory and same behavior is also shown in the future. This addiction is linked to NPY neuropeptide levels which can be found in Drosophila where these neuropeptides

considered a tradition. Research of these flies initially entered labs 100 years ago. Thomas Hunt Morgan‚ who lived from 1866 to 1945‚ was the founder of drosophila genetics. Thomas preformed his research in Morgan lab at the Columbia University in 1910. Here was when they found a famous mutation‚ know as the white-eyed fly. Quite an accomplishment was this discovery‚ but the end of the 1980’s there were 3‚000+-recorded mutations. Now drosophila is very popular; so popular‚ it would be almost impossible

Drosophila melanogaster - Sex linkage and inheritance of genes through cross breeding Abstract This experiment looks at the relationship between genes‚ generations of a population and if genes are carried from one generation to another. By studying Drosophila melanogaster‚ starting with a parent group we crossed a variety of flies and observe the characteristics of the F1 generation. We then concluded that sex-linked genes and autosomal genes could indeed be traced through from the parent generation

BIOL 323-02 TTH 12pm-2pm Drosophila melanogaster: Monohybrid Cross & Sex-Linked Inheritance October 6‚ 2012 Abstract This lab involved a monohybrid reciprocal cross and a sex-linked cross utilizing Drosophila melanogaster fruit flies. After sexing the flies‚ placing them in media‚ and letting them cross breed‚ we analyzed and recorded the phenotypes that were observed. The P1 flies were anesthetized then sexed by observing their phenotypes and equally distributed
