ratio, and that the traits would be autosomal, unlinked recessive as well. This hypothesis was also rejected due to the test statistic, 89.95, being larger than the critical value, 7.815. White eyes are found to be a recessive, sex-linked trait in Drosophila Melanogaster; the amount of males having white eyes is significantly higher than the amount of females. In Table 1.2 we see that the amount…

In order to be able to determine whether the drosophila Melanogaster fly cross will follow Mendel’s law of Independent assortment in a 9:3:3:1 phenotypic ratio a dihybrid cross was performed of cinnabar brown flies with wild type flies. It was observed that the mutant phenotypes became visible in the second filial generation, thus following the law of independent assortment in the first filial generation. It was also concluded that in the first filial generation the dominant genotypes masked the…

The results show that the protein derived from the Drosophila cDNA sequence and the human protein share the same domain, also, there is a high degree of homology between the two proteins. Therefore, the Drosophila Melanogaster plasmid DNA sequence codes for a protein that has a human homologous involved in human physiology. Researchers are still investigating the function of my protein in Drosophila Melanogaster. However, the function of the homologous protein in human is pretty clear. Indeed,…

Introduction This experiment was designed to examine inheritance patterns in Drosophila melanogaster. Three crosses were set up to examine the inheritance of eye color, body color, and wing shape. The mutant males used in this experiment had: sepia eyes with ebony bodies, white eyes and yellow bodies, or sepia eyes with vestigial wings. All of the females were wild-type. It was also confirmed that the females being used were virgins. This fact was important since female flies can store the…

utilized for many purposes, which include genes, genotyping, sequencing, cloning, etc. (Kelly, 2016). This allows for the ability to conduct DNA analysis revealing varying compositions and properties. For the following experiment the genomic DNA from Drosophila melanogaster, was utilized to be cloned and sequenced for either actin or 18s rRNA. In order to clone and sequence the specific section of DNA 9 specific steps had to be conducted and they are as follows: extraction/purification of DNA,…

2.RELATED WORK The artificial bee colony (ABC), an optimization technique is based upon the intelligent moving behavior of honey bee swarm was proposed by Karaboga in 2005. This kind of new Meta heuristic is inspired by the clever foraging behavior of honey bee swarm. The criteria presented in the work is for numerical function optimization. The advantage of ABC is that the global search ability in the algorithm is implemented by introducing neighborhood source production mechanism. Rao et al.…

The English Peppered Moth and Natural Selection Lab By: Justin Pascual Partners: Nathan Magbitang, Rudy Keyes-Krysakowski, and Glenn Tipold Teacher: Ms. Coopman Date Performed: November 16, 2015 The English Peppered Moth and Natural Selection Lab Purpose The purpose of this lab is to determine how variation in a population can favour survival of a certain trait over multiple generations. Hypothesis It is believed that if there are more speckled moths remaining in the tray at the end…

This article caught my eye in the first place because it reminded me of the apple magot fly simpatric speciation that we have studied and understood quite clearly in class. My first response to the whole simpatric and allopatric speciation was clear and it seemed to me that the apple maggot fly speciaton proved this concept. However simpatric speciation with the jays are considerably more unexplanitory, complicated, and as the article indicates, "weird". Katie Langin is the biologist in this…

The main goal inathe experiment was to determine theainheritance pattern of aaparticular mutation. A asecondary goal in conductingathis lab was to study and comprehend mendelian genetics. In this experiment, Drosophilaamelanogaster, commonlyaknown as fruit flies, were used to studyaand understand the principles of mendelianagenetics. D. melanogasterawas also used as a model to identifyathe patterns of inheritance of certainamutant traits in fruit flies. Mendel’salaw ofasegregation is important…

The unknown mutant of Drosophila melanogaster numbered 948 displayed eye characteristics different from the wild-type. The most prominent difference in mutant 948 eye compared to the wild-type eye appeared to be its size and color. The mutant Drosophila eye is smaller in size and has a darker red pigmentation. In addition to these variable phenotypic characteristics, the mutant 948 has more ocular shaped eyes and its outer bristles on the lateral side of each eye are significantly less…
