Lab 6. Drosophila cross( start) Melat Mebrahtu Lab Instructor: Professor Hicks Principles of Biology Lab II‚ Wednesday 1:00 am- 2:00 pm Abstract The goal of this experiment was to examine the Drophisila fly cross for which the result was seen in two weeks .The Drosophila melanogaster has been a model organism that was experimented in the laboratory. It is a small fruit fly that feeds on and lives on spoiled fruit. It is one of the most valuable organisms in genetics

Purpose To provide practice in using appropriate methods to answer questions and solve problems about monohybrid inheritance. Questions Q1 Some forms of albinism‚ a genetic disorder‚ may be due to a single gene mutation. The allele for albinism is recessive to the allele for no albinism. A woman is heterozygous for albinism. Her male partner is homozygous for the ‘normal’ allele. a Does the woman suffer from the condition? no b What percentage of their children are likely to be carriers

BIOL 323-02 TTH 12pm-2pm Drosophila melanogaster: Monohybrid Cross & Sex-Linked Inheritance October 6‚ 2012 Abstract This lab involved a monohybrid reciprocal cross and a sex-linked cross utilizing Drosophila melanogaster fruit flies. After sexing the flies‚ placing them in media‚ and letting them cross breed‚ we analyzed and recorded the phenotypes that were observed. The P1 flies were anesthetized then sexed by observing their phenotypes and equally distributed

In my lab experimentation‚ all of the parent generation‚ or flies I started with‚ were wild-type or mutant phenotypically‚ but their genotypes were unknown. However‚ after I mated these flies and they produced offspring‚ the parental genotypes could be hypothesized based on phenotypic observations and ratios of the F1 and F2 generations. I then could check my observations by testing it using the Chi squared (X2) test. A. Miniature Wings – (Sex-Linked Recessive) To determine the inheritance of

3 The Importance of Elections as a Linkage Institution and Voting Linkage institutions can be defined as institutions that connect citizens with the government. Examples of linkage institutions include elections‚ political parties‚ interest groups‚ and the media. Elections specifically are supposed to encourage public participation in the selection of governmental officials. Unfortunately‚ low voter turnout has proved that elections are an imperfect linkage institution. Elections depend on voters

. a. Association: linkage among variables b. Positive Association: values of two different variables increase simultaneously c. Negative Association: inverse; one variable’s value increases as the other decreases d. Non-linear Association: curvilinear; un-proportional increases/decreases between two variables e. Dose-response Relationship: correlative association between an exposure and effect 2. A non-causal association is when one variable is related to but doesn’t cause the other variable (outcome);

RURAL –URBAN LINKAGES‚ THEIR ROLE IN SUSTAINABLE DEVELOPMENT. BY:LADYANGE INTRODUCTION Although policy makers and the development community have widely used the phrase “rural development. The concept of rural development has changed significantly during the last 3 decades. Until the 1970s‚ rural development was synonymous with agricultural development and‚ hence‚ focused on increasing agricultural production. This focus seems to have been driven primarily by the interests of industrialization
