Genevieve 171L Honors 11/6/08 Characteristics of the Aldox Gene Introduction This experiment was conducted by using aldehyde oxidase (AO) to genetically characterize the aldox gene. It was hypothesized that the aldox gene is recessive and sex linked. Fruit flies (Drosophilia melanogaster) are genetically well known eukaryotic organisms that were used to investigate the inheritance of the aldox gene. To determine if AO is present, an enzyme spot test was used. The yellow color indicated that AO was present and active while blue color indicated AO is not present.
Drosophila Lab Eric Johnson 11/19/09 Dr. DelliPizzi Genetics Abstract: In this lab the genetics of Drosophila Melanogaster, also known as the common fruit fly, was examined. Several experiments were performed including crossing ebony flies with vestigial, as well as flies with red eyes and white eyes. The data was collected over a period of 2 months of breeding. The F2 generation of flies in each experiment was also bred to discover what kind of crosses it would produce. In order to perform this experiment first virgin flies had to be attained by separating all adults from the stock vials and quickly separating the newly hatched egg larva into male and female containers.
“Therapeutic cloning creates human embryos through cloning in order to harvest their stem cells for medical research; reproductive cloning creates the embryos for human reproduction”. (Hansen 880) Both cloning procedures begins by removing the nucleus from a female egg cell and a somatic (body) cell to remove its genetic material. The nucleus of the somatic cell is then transferred to the denucleated female egg. At last, the egg is stimulated by a small amount of electricity that tricks the egg to
It can also be a combination of the two (“Genetics + Environment = Variation”, this can also be referred to as “Genotype + Environment = Phenotype”, this is because phenotype which is the visible characteristics of an individual can be affected due to changes in the environment (i.e. climate). In terms of genetics, variation is brought about through sexual reproduction (i.e. the assortment of the parental chromosomes and random fertilisation of the egg and also through Meiosis where crossing-over of the chromosomes can occur during Prophase I. Genetic variation is therefore something that is inherited.

Malfunctioning patch leads to defective embryonic development and many types of skin cancer. Apoptosis is controlled cell death; patched is responsible for that too. When this gene does not work tissue structure is not maintained, embryo's toes and fingers do not take shape, and skin cancer can grow unchecked. Hedgehog, the gene that turns on the patched gene, can also lead to skin cancer when it does not function. The gene product of hedgehog is a protein that rests on the cell membrane and sends signals to the nucleus of the cell.
Drosophila Inheritance Patterns Gage Howard May 7, 2012 Honors Genetics Mrs. Jennings ABSTRACT INTRODUCTION The purpose of this experiment was to determine the inherited patterns of the eye color and the types of wings of all of the fruit flies, Drosophila melanogaster. The wild type phenotype eye color is red, and the mutant eye color is sepia, a brownish- black color. The wild type phenotype wing shape is elongated, and the mutant wing shape is shorter and crinkled. The Drosophila melanogaster has four chromosomes. The gene that has a mutant inheritance it is found on chromosome two and three.
Genes can help determine the ancestry or heredity of an individual. For example there was a study done on admixed populations, which helped to explain how genes work together to control the full range of phenotype diversity, which provides new insight into the evolution of these traits, and a model for understanding of quantitative variations. (Dermatol Arch,2010, pg2) Third, gene mutations are germ-line meaning that they are passed from parent to child, or caused by UV light. For example a person can be born with a genetic mutation in all of their cells which are germ-line. individuals can also acquire a mutation in a single-cell during their lives by environmental patterns, such as UV light exposure.
