Abstract The main purpose of this experiment was to find which chromosome our unknown gene mutation is presented on and the exact location on that chromosome. In order to do so many cycles of crosses were completed using linkage analysis on Drosophila melanogaster‚ a type of fruit fly used in this experiment to identify our unknown gene mutation‚ unknown. Using virgin bar females crossed with Curly/Plum; Dichaete/Stubble male fruit flies represented our Discriminant Cross one (DC1). The

The Selfish Gene Author: Richard Dawkins Book Criticism •“Genes cannot be selfish or unselfish‚ any more than atoms can be jealous‚ elephants abstract or biscuits teleological. This should not need mentioning‚ but Richard Dawkins’s book The Selfish Gene has succeeded in confusing a number of people about it” (Midgley). •There are many things to disagree with in the book‚ depending on one’s viewpoint. Some people may interpret the term “selfish gene” in a literal way‚ believing that

Hox Genes | November 15 2010 | | Comparative Vertebrate Anatomy | Homeotic complex (Hox) genes are defined as a group of related genes that specify the anterior-posterior axis and segment identity of metazoan organisms during early embryonic development. These are situated very close to one another on the chromosome in groups of clusters. The orders of these genes located on the chromosomes are the same as the expression of the genes in the development of an embryo‚ whereas the first

Genetics Experimental Analysis Set #2 Linkage 1. In gorgonzolas‚ there are three recessive traits that affect the organism’s appeal: shrunken fruit‚ foul-smelling flowers‚ and short height. A heterozygote was crossed with a homozygote‚ yielding the following offspring: 46 - foul-smelling 44 - shrunken fruit‚ short height 8 - short height 8 - shrunken fruit 7 - foul-smelling‚ short height 6 - foul-smelling‚ shrunken fruit 3 - foul-smelling‚ shrunken fruit‚ short

Associate Program Material Genetics Worksheet Review the images below and answer the follow-up questions. Questions: 1. According to the pedigree‚ is cystic fibrosis inherited as a dominant or as a recessive trait? Explain how you made your conclusion using evidence from the pedigree and the principles of genetics. -Cystic fibrosis is inherited as a recessive trait. Each child of 2 carriers has a ¼ chance of inheriting

A particularly important category of genetic linkage has to do with the X and Y sex chromosomes. These not only carry the genes that determine male and female traits but also those for some other characteristics as well. Genes that are carried by either sex chromosome are said to be sex linked. Men normally have an X and a Y combination of sex chromosomes‚ while women have two X’s. Since only men inherit Y chromosomes‚ they are the only ones to inherit Y-linked traits. Men and women can get

Gene Splicing What Is It? Gene Splicing is one type of genetic technology. It is the process of taking pieces of DNA from one or more organisms then combining them into another DNA strand to create new DNA or recombinant DNA. How does it Work? Chemicals called restriction enzymes are used as scissors to cut the DNA. Thousands of these restriction enzymes exist‚ each recognizing only a single sequence of DNA. Once it finds that sequence in a strand of DNA‚ it attacks it and splits the base pairs

after climate change damage and the history of policies that have been made in response to economic climate change. Once these points have been clearly assessed and explained‚ the next step is to ponder possible solutions to prevent these scenarios from happening. The economics of climate change is mainly focused on our future generations who will be affected by the decisions made in the present time. Climate change is not seen as so urgent as it is stressed when it is viewed in a small span of time

Gene Therapy What is it? If genes don’t produce the right protein or don’t produce it correctly a person can have a genetic disorder. Gene therapy is an experimental technique that involves the transfer of a working copy of a gene into a cell to repair or replace a faulty gene so it is able to produce functioning proteins again. There are several approaches. The most common one is to insert a normal gene to replace the non-functional gene. Another approach is to swap a non-functional
