AP Lab Seven Genetics of Organisms Dan Torres AP Biology Block 1 January 24‚ 2011 Introduction & Background Fruit flies have made a huge contribution towards knowledge about genetics‚ but for most people‚ they are just annoying insects that are attracted to their fruit. Their scientific name is Drosophila melanogaster‚ and to scientists‚ they have been a key to understand many principles of heredity including sex linked inheritance‚ epistasis‚ multiple alleles‚ and gene mapping. Fruit

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle

Outline for Chapter 10 Define the following terms… What is Evolution? (Section 10.1‚ pp 222-224) Figures to review: 10.1‚ 10.2 Biological evolution • Biological evolution is defined as any genetic change in a population that is inherited over several generations. These changes may be small or large‚ noticeable or not so noticeable. Species • the major subdivision of a genus or subgenus‚ regarded as the basic category of biological classification‚ composed of related individuals

Wild type (heterozygous for normal wings and red eyes) × recessive homozygote with vestigial wings and purple eyes 74) What pattern of inheritance would lead a geneticist to suspect that an inherited disorder of cell metabolism is due to a defective mitochondrial gene? Answer: The disorder would always be inherited

Now moving on to analogous structures‚ which are structures that have no common origin but are similiar in function. an example would be a butterfly wing to an eagle’s wing they help you fly but are different origins. So would Red Bull count? Ah! That is right‚ you don’t know about Red Bull! Let’s

same color. After eclosion‚ the mutant expressed a slightly darker pigment than the wild-type. Hours later‚ the expressivity of the mutation increased‚ and the female and male mutants had a noticeably darker pigment than the wild-type on the legs‚ wings‚ head‚ and overall body. Because of the darker pigment‚ the mutant will henceforth be referred to as darkydark. The wild-type and darkydark fly had a dark brown stripe on the inferior part of tergites one through four‚ but the wild-type had a lighter
