Effects of HW Violations on D Melanogaster Alleles?
The interaction between genetic variation and natural selection is one of the most important concepts in modern biology. The product of this interaction, evolution, which is a change in a population's allele frequency, is responsible for the great complexity and diversity of life seen on earth today. Allele frequencies of a non-evolving population (one in which the allele frequencies are not changing) can be elegantly modeled using the Hardy-Weinberg theorem. For a population to be at equilibrium, five conditions must…...

A Laboratory Report on an Experiment About the Genetics of Fruit Flies
This lab's purpose was to determine the genetics of fruit flies, including but not limited to: raising them, feeding them, mating them, sexing them, separating them, and mating them again. We then had to determine which traits were dominant in flies, in my case either the wild eyes or the white eyes, by crossing the flies and through phenotypic ratios we were to determine genotypes. My partner was Eugene Montoya. We chose the white flies because they were more attractive…...

Eye Color Pigments Drosophila Melanogaster
The eye color pigments of Drosophila melanogaster are composed of red and brown pigments. The purpled eye color of purple (pr) mutants is the result of a defect in the synthesis of the wild-type pigment, drosopterins (Kim, Yim 1995). Drosopterins are produced non-enzymatically by the condensation of PDA with 7,8-dihydropyran (Brown 1986). The pathway leading to the biosynthesis of drosopterin was proposed by two scientists named Brown and Dorsett. The first step in drosopterin biosynthesis is the formation of H2NTP…...

Study of Drosophila Melanogaste
Genetics has many different fields of research, and one of the mcontenderost common organisms used for a better understanding is the Drosophila melanogaster. A discovered unknown mutant of the fruit fly differs phenotypically in eye coloration compared to the wild type. Wild type D. melanogaster tends to have vibrant red eyes with a slight black pseudo pupil (Figure 1, A). On the other hand, the unknown mutant has darker maroon eyes and no apparent pseudo pupil (Figure 1, B). Without…...

Toxicity of Nanoparticles
Nano-technology is Nano-sized debris that has been produced as a direct result of human activity (Griffin et al., 2018) Current advances in materials synthesis and characterization technology have led to an explosion within the production of nanomaterials. Nano-technology has introduced a notable revolution within the commercial quarter. Because of their special physicochemical and electric houses, Nanosized materials have won vast attraction within the area of electronics, biotechnology, and aerospace engineering. Within the discipline of medication, NPs are being hired as…...

Mendelian Genetics and the Dihybrid Cross of Drosophila Melanogaster
Genetics is a widely studied topic in science. The purpose of this experiment was to analyze and determine the dihybrid cross between drosophila and the mutations that are common. Because they have a very short reproduction period, Drosophila are commonly used to analyze mutations and dominant/recessive traits. Gregor Mendel introduced Mendelian Genetics, and Mendel’s dihybrid cross is used as reference to compare the mutation combinations for the offspring Drosophila (Holmes, 2006). Based on the class results from crossing the heterozygous…...

The Drosophila Melanogaster Mutations
The following sample essay on The Drosophila Melanogaster Mutations offers an extensive list of facts and arguments related to it. The essay's introduction, body paragraphs and conclusion are provided below. Drosophila melanomas are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled, they have a short life cycle and they are easy to keep large numbers such as the confined spaces of a laboratory or…...
