The purpose of this experiment was to determine the F1 genotype of fruit fly traits using the phenotypic ratio of the F2 generation and to express these results of the unknown cross through a Chi-square model and Mendelian genetics. After the experiment‚ it was found that the parents held a heterozygous genotype through using the Chi-square model‚ and that the observed and expected values fall within the Chi-squared value which also falls into the p-value. The Chi-squared value was 5.64‚ the degrees

Alice’s conversation with Humpty Dumpty‚ another non-human creature‚ further demonstrates the power structure of language. Humpty Dumpty demonstrates the malleability of language when he gives words his own definitions‚ such as when he defines glory as “a nice knock-down argument” (244). Alice says to him that that is not what the word glory means‚ in response to which Humpty Dumpty says‚ “[w]hen I use a word […] it means just what I choose it to mean – neither more nor less” (244-245).

Surveying is believed to be the third oldest profession in the world. To a surveyors‚ the link chain symbolizes a rugged era‚ in terms of evolution of surveying technology and equipments. The chain was a precision part of a surveyor’s equipment for years. Then the Renaissance in education and scientific knowledge provided the necessary intellectual foundation for the development of modern surveying. With the advent of the electronic distance meter‚ GPS‚ GIS‚ and computer-controlled Land Surveying

Drosophila melanogaster: Mutant Fruit Flies Jessica E. Phillips Genetics 3301 April 13‚ 2012 Introduction: Drosophila melanogaster better known as the fruit fly can be found near rotting fruits‚ vegetables‚ or anywhere where there is food that has rotted and or fermented. (Potter‚ 2010) D. melanogaster has four different stages in its life cycle. The first stage of D. melanogaster is the egg which can last for about one day; then turns into a larva. The larva stage last for about 7-8 days

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‚

The major sexual differences in Drosophila are apparent in the abdominal segment of the flies. In males‚ the last abdominal segment of the male is much larger and rounded than that in the female. Another indicator is the presence of sex combs present in males. Male flies has a small‚ densely

have used visual techniques to bring to life what is the darker side of a big city. The cityscape presented in A Detective Story is washed with black‚ grey and sepia tones consistently when different aspects of the city are focussed upon. The use of these three colours in combinations give the city and older and dirtier look due to sepia bring associated with age and decay as well as black and grey being associated with uncleanliness and darkness.
