Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene

Investigation | May 28 2013 | Drosophila melanogaster lab experiment Question: How do the dominant or recessive genes in particular traits in a cross between a male and female Drosophila determine the traits of its offspring? Aim: to establish whether characteristics produced from the offspring of a drosophila cross are recessive or dominant traits. Hypothesis: If certain phenotypes are expressed in the offspring from the cross of certain Drosophila‚ then the determination or justification

In this population cage‚ it used Drosophila melanogaster because is a common model organism for genetic studies. In this population cage‚ it was calculated the coefficient of selection of an actual sample and an ago sample. In this experiment‚ it was used the actual sample #4 and the ago sample #3. The result of the coefficient of selection should be at the rate between 0 and 1. The result was 0.82‚ so it was a good result of the coefficient of selection between these two samples (#4 and #3).

Abstract: Enzymes help determine a phenotype through proteins. The experiment presented tests how enzymes affect the pigment in the eye of Drosophila. What was resulted in this experiment is that when certain enzymes change‚ a mutation is created‚ causing the change of pigments in the different Drosophila’s eyes. The production of one enzyme is one gene and a mutation of this gene can cause an enzyme to be inactive which leads to the phenotype changing. Introduction: George W. Beadle and Edward L

METHODOLOGY To prepare for the experiment‚ place solvent into a test tube‚ so that the level of solution

throughout decaying food. The topic that is being examined is the Drosophila. When Drosophila is prepared for mating or hatching‚ they have a full lifecycle of about 20 days‚ thus are the models for relating sex-linked inheritance. Obviously it is not the breeding ways of the Drosophila that is being examined in this experiment‚ but the developing offspring‚ and their phenotypes. The phenotype is based on the wing shape and the eye color‚ which is resulted by grouping of genes

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 light (Figure 2). Sample B was a brown-eye phenotype

On April 5 1968 Jane Elliot preformed the famous experiment in her classroom separating blue-eyed and brown-eyed students. She had separated them by making one eye group inferior to the other making them have certain benefits and better treatment than the other
