    organism in laboratories due to the many advantages that the organism provides: short generation time, sexual dimorphisms, cost effectiveness and easiness to maintain, amongst others. The generation time of Drosophila is around 9 – 11 days, and phenotypes in men, such as sex combs, heavily pigmented abdomen, and shape of abdomen and size, makes of Drosophila melanogaster an effective organism to study. In Drosophila melanogaster, the males do not go through crossing over during meiosis, which…

    the flies in the mixture were too coated in the solution to be sexed and analyzed for phenotype. To find a solution and to act on these errors, improvements could be made to increase accuracy when creating the food mixture for the vials. Another mistake was made when a group member knocked the dish containing the male flies in the F2 generation onto the floor. The flies were not yet counted or sorted by phenotype so the number retrieved from the floor could not be certain. This could be improved…

    which is made up of astrocytes, oligodendrocytes, and glial progenitor cells create a problem with creating precise structural reconstitution with stem cells. Neurological diseases including Alzheimer’s and Lewy body entail a multitude of neuronal phenotypes. This diseases exhibit both contiguous and transsynaptics patterns of spreading, which causes them to be poor targets for neuronal replacement strategies as they cannot be targeted.…

    The apterous gene mutations is a recessive trait that is inherited causing a varying phenotypes such as different wing deformities. Other phenotypes observed are the decrease in life span and female sterility. Ap is required to regulate gene expression needed for the development of Drosophila wings and haltere discs. Decreased ap activity due to the overexpression of dLMO results in wing mutations. The phenotypes displayed in apterous mutants are places them at a disadvantage compared to wild…

    were from the exposure of the fruit flies to radiation. Seven readily identifiable phenotypes are used in the classroom for fly culture. Three sex-linked phenotypes are yellow, white, and bar whereas four autosomal phenotypes are vestigial, sepia, ebony, and apterous (Carolina Biological Supply Company, 2005). Objective The purpose of the experiment was to figure out the parental cross by using the observed phenotype in filial generation 1 (F1) and the ratio of F2. The experiment was conducted…

    In Junot Diaz’s The Brief Wondrous Life of Oscar Wao we get a greater glimpse into the politics of phenotypes and authenticity in Dominican culture. More specifically in its relationship to blackness. In Irene Lopez, a Puerto Rican clinical psychologist’s essay, Puerto Rican Phenotype: Understanding Its Historical Underpinnings and Psychological Associations, she posits that, “Puerto Ricans who consider being “Indian” more beautiful, or more authentic, than being Black and, thus, often prefer to…

    Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) make up the nucleic acid in cells and is responsible for the differences in many of our traits. DNA is the substance in which our genetic material is carried on from one generation to the next. Nucleotides join together through phosphodiester linkages between the 5 ' and 3 ' carbon atoms to form nucleic acids. “Nucleotides are composed of a five-membered sugar group with a purine or pyrimidine nitrogen base group attached to its 1 ' carbon…

    There are several genetic variants in the DNA sequence of the ABO gene that give rise to ABO subgroups. The most important of these are the A1 and A2 subgroups, which differ in the activity of their transferase enzyme gene products. The transferase activity in A2 individuals is less efficient in catalyzing the formation of the A antigen from the H antigen compared with those in the A1 subgroup, resulting in lower expression of A antigen. Type A2 individuals have relatively fewer Type I, Type III…

    ratios of the phenotypes in the F1 generation would be completely random and follow the laws of segregation and independent assortment. Under such assumption, the 3 genes examined in this experiment would not be linked, and the final observed number of F1 flies with each phenotype would equal the expected number under the null hypothesis. The expected number in each case was half the total number of flies for phenotypes that were possible in the offspring based on the parental phenotype. This…

    Hot Cheeto Research Paper

    The affected phenotype in the mutant hot cheeto is the bristles. The affected bristles are gnarled, dark, and bending to the side of the scutum. The tip of these bristles look melted. The sizzled appearance of the phenotype makes the name of hot cheeto appropriate for this mutant. The bristles of the wild type Drosophila melanogaster are long, slick, and black. The posterior scutellar bristles in D. melanogaster are two long bristles attached to the end of the scutellum and projected in an…
