stimulus that helps it search for the food (Stocker et al. 2007). There are flies such as dragon‚ house flies and various other flies in diptera order. Flies are attracted to sugar and seem to have certain neurons that activate upon encountering the sugary content. The compounds contained sugars‚ salts‚ bitter food‚ and certain other Molecules are detected by gustatory neurons‚ which are widely distributed in the body of the fly (Stocker et al. 2007 ). Neurons that influence feeding behavior are present

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

Lab 02-Mendelian Inheritance 1. Introduction The purpose of this lab is to learn how to use Mendel’s Laws of Inheritance to generate expected phenotypic ratios of F2 generation. In order to do this‚ we cross true-breeding parents to generate F1 generation and then inter-cross the F1 generation to yield F2 generation. Then‚ we test the efficiency of the expected phenotypic ratios generated by comparing them with the observed phenotypes of randomly selected F2 generation. 2. Methods • Perform a monohybrid
