Genetics includes the study of heredity, or how traits are passed from parents to offspring. The topics of genetics vary and are constantly changing as we learn more about the genome and how we are influenced by our genes. Inheritance Mendel & Inheritance – powerpoint presentation covering basics of genetics Simple Genetics Practice – using mendelian genetics and punnett squares Genetic Crosses with two traits – basic crosses, uses Punnet squaresGenetic Crosses with two traits II – basic crossses, uses Punnett squaresDihybrid Crosses in Guinea Pigs (pdf) – step through on how to do a 4×4 punnett square Codominance & Incomplete Dominance – basic crosses involving codominance X-Linked Traits – practice crosses that involve sex-linkage, mainly in fruitflies The Genetics of Blood Disorders – a worksheet with genetics problems that relate to specific disorders: sickle cell anemia, hemophilia, and Von Willebrand disease.

Evolution & Taxonomy Evolution is often called the “unifying theory of biology” because it organizes all of the observations gathered by biologists and proposes and explanation for those observations. All state standards for teaching science include a section on evolution (sometimes called adaptation or change over time). Evolution Peppered Moth Simulation – newspaper and colored paper simulated natural selection Peppered Moth Simulation Kit – similar to above, only uses a purchased kit from Neo Sci. Evolution Concept Map – graphic organizer, shows terms related to evolution and how they are connected Evolution Crossword Puzzle – terms related to topic of evolution; darwin, galapagos, selection..etc… – Berkeley interactive activity with questions Comparing Life History to the Hours of a Clock – place events, such as “bacteria evolve” on a clock The Decay Curve of Twizzlers – use twizzlers candy to understand the decay of isotopes and how that decay is used for carbon dating Taxonomy

Honors Genetics Use of our material: We have worked very hard on Powerpoints/games/worksheets, etc to make this a resource for our students. If you are using our materials, please give us credit for our efforts by listing us as a source with links to our site. High School Life Science Conceptual Understanding: Heredity is the passing of characteristics from one generation to the next via genes. Chromosomes are single long DNA molecules which carry the instructions for forming particular species characteristics. Genes are a segment on the DNA that code for a particular trait. An alternative form of a gene found at the same place on a chromosome is called an allele. HS-LS3-1 Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring. High School Life Science Standards (Grades 9-12) Indicator 1: Understand the fundamental structures, functions, classifications, and mechanisms found in living things.

British Couple Clones Dead Dog For $100K On Dec. 26, Laura Jacques, 29, and Richard Remde, 43, of Yorkshire, United Kingdom, welcomed two new puppies - dubbed Chance and Shadow - cloned from the DNA of Dylan, their deceased boxer, the Guardian reports. Dylan died of a brain tumor in June at the age of 8. [READ: Do You Love Your Dog More Than Humans?] The couple sent his DNA samples to Sooam Biotech Research Foundation in South Korea, which offers a commercial dog-cloning service for about $100,000 per procedure, according to the Guardian. Sooam Biotech, the only laboratory of its kind in the world, has successfully cloned hundreds of dogs, though Dylan's is reportedly the oldest sample from which a dog has been cloned successfully.

Un modèle théorique de l’évolution de l’œil chez les vertébrés. L'œil est un système sensoriel utilisé dans l'ensemble du règne animal. Diversité des yeux[modifier | modifier le code] Environ 1/3 des 33 embranchements animaux existants possèdent des organes photosensibles, et un autre tiers possèdent des yeux, le dernier tiers n'ayant a priori pas d'organes spécialisés dans la détection de la lumière[1]. Diversité fonctionnelle[modifier | modifier le code] Les yeux, s'ils permettent tous de percevoir et d'analyser la lumière, n'en retirent pas tous les mêmes informations. Diversité structurale[modifier | modifier le code] Toutes les structures de l'œil présentent une variabilité, parfois associée à différentes fonctions : Il existe de nombreux pigments différents, composés d'une opsine (5 classes différentes chez les vertébrés) et d'un chromophore (2 différents).

Current Classes Practice Exams for Genetics These practice exams were put here to help you monitor your progress in genetics. Do not study only these questions as new questions will be written for each test and old questions will be modified. It is important that you understand the question and why the correct answer is correct. Exam #1 Chapter 2 -- Chromosomes and Cellular Reproduction Chapter 3 -- Basic Principles of Heredity Chapters 4 and 6 -- Sex Determination, Sex-linked Traits, Pedigrees Chapter 3 -- Probability and Statistics Exam #2

Théorie synthétique de l'évolution Un article de Wikipédia, l'encyclopédie libre. Pour les articles homonymes, voir TSE. La théorie synthétique de l'évolution Histoire de la théorie synthétique de l'évolution[modifier | modifier le code] Définition[modifier | modifier le code] Aujourd'hui, l'évolution n'est plus envisagée comme la transformation d'individus isolés mais comme celle de groupements d'individus de même espèce, c'est-à-dire des populations. Une population évolue quand la fréquence d'une version d'un gène appelée allèle (ou de plusieurs allèles) s'y modifie. Lorsque l'ensemble des individus qui constituent une espèce forme plusieurs populations isolées, chacune de ces populations peut acquérir des caractères particuliers et donner naissance à des variétés différentes au sein de la même espèce. La "barrière" qui sépare les variétés d'une même espèce peut être de nature variée. L'évolution, faits et théorie[modifier | modifier le code] Le membre antérieur de tous les Vertébrés présente une structure analogue.

Anatomy (Dissections) Most biology classes will have some form of dissection – the frog is the most common. However, if you do not do an actual dissection, many of the sections below contain links to virtual dissections and image files. Fetal Pig Fetal Pig Dissection - procedure for the dissection Fetal Pig Dissection Review - resources for studying Fetal Pig Lab Guide – lists structures and check boxes Fetal Pig Gallery – collection of labeled and unlabeled images Frog Dissection Frog External Anatomy - legs, eyes, mouth structures Frog Dissection - major organs of the digestive, urogenital, and circulatory and respiratory systems Frog Brain and Bones – remove the frog’s brain, expose the bones of the lower leg Frog Dissection Crossword – review terms and procedures Observe a Living Frog – non dissection, behavior and characteristics Bullfrog Dissection – bullfrog dissection guides, more advanced than basic frog dissection Frog Dissection Gallery – collection of labeled and unlabeled images of the frog Human

Fruit Fly Tutorial Index In this virtual lab we will cross various fruit flies to see what phenotypes are present in the F1 and F2 generation. Using the data from these crosses, we will make a hypothesis regarding the genotypes of the parental (P) generation and test the hypothesis using a chi square analysis. **Print out a copy of the Data Page **Review how to do a chi square analysis Background Information Drosophila melanogaster is a fruit fly, a little insect about 3mm long, of the kind that accumulates around spoiled fruit. It is also one of the most valuable of organisms in biological research, particularly in genetics and developmental biology. See mutant fruit flies You can order mutant fruit flies from any biological company and perform crosses in the lab that will generally take about two weeks. How to Raise Fruit Flies 1. Terminology Wild-type - flies that have the "normal" characteristics, red eyes, normal length wing and brown bodies. Mutant flies - any variation from the wild type. Genetic Notation 1.
