to effectively grow (Whitehead, 2010). Based on the data gathered from this experiment, a farmer, gardener, or botanist may wish to re-examine his or her methods of hormone usage and respectively change the ratios he or she uses, based upon which phenotype of seed has been planted. Throughout a plants life, its development and overall sustainment of life are conducted by the release of hormones. They direct the growth and development of the plant as well as the fruits and vegetables humans…

Evolution of Multiple Traits through Multiple Mutations at a Single Gene” by Catherine R. Linnen et al. the article discussed how mutations of multiple traits from a single gene led species to thrive in their environment. The research was based upon the phenotype of light-colored mice being selectively advantageous on the sand soils of Nebraska Hills. The fur of the mice evolved into a light- pigmentation to prevent from being attacked by predators. Researchers hypothesized the light-colored fur…

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 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…

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…

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…

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…

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…

phenotypic class of the mutant allele. As progeny began to appear in the cross, we began keeping a count of how many flies per mutations were produced in the laboratory notebook. After we collected over 200 progenies, we counted how many of each phenotype was shown and conducted a chi-square test with the aid of Microsoft Excel. A chi-square test allows scientists…

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…
