This experiment is going to test the hypothesis that there will be more number of flies with normal wings at the food site than the number of vestigial wings. Materials’ List: - A vial of flies with vestigial wings. - A vial of flies with normal wings. - A plastic box with holes on two sides and top. - One vial. - Three foam plugs. - Tape. - Well

A Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster‚ more commonly known as the fruit fly‚ is a popular species used in genetic experiments. In fact‚ Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can

In this lab‚ you will learn about homologous‚ analogous‚ and vestigial structures and their value as evidence for evolution. INSTRUCTIONS A. HOMOLOGOUS STRUCTURES There are many examples of body structures that are formed in similar ways during embryonic development and that share similar patterns of bone structure

the principles of independent assortment‚ which states that allele pairs split independently during the making of gametes. This means that the traits are transmitted to the offspring independently‚ like in this case the white eye gene and the vestigial wing gene (C.

Genetics of Organisms Nicole Ryan AP Biology 2/2/15 Block 1 Introduction and Background Drosophila melanogaster or more commonly referred to as “fruit flies” have been used for genetic research for over 100 years. During his time at Harvard university‚ Charles W. Woodworth is credited with being the first to suggest fruit flies be used for genetic research. A century later‚ fruit flies are the most widely used eukaryotic organism for genetic research (Drosophila)

cross-performed was Ebony Bodies versus Vestigle Wings‚ where Long wings are dominant over short wings and normal bodies are dominant over black bodies. The other cross that was performed was White versus Wild where red eyes in fruit flies are dominant over white eyes. The purpose of the first experiment‚ Ebony vs. Vestigle was to see how many of the offspring had normal bodies and normal wings‚ normal bodies and vestigle wings‚ ebony bodies and normal wings‚ and ebony body and vestigle wings. The purpose

Part A 1. Thermally immobilize a vial of wild-type Drosophila. Your instructor will demonstrate the proper immobilization technique. 2. Observe the flies’ traits‚ particularly body features that distinguish males and females‚ eye color‚ and wing size and shape. Record your observations in Table 1 in the Analysis section. If‚ at any time during your observations‚ the flies begin to become active‚ re-immobilize them according to your instructor’s directions. Part B 1. Obtain a vial of a
