Chapter 11: Complex Inheritance and Human Heredity RECESSIVE GENETIC DISORDERS -A recessive trait that is expressed when the individual is homozygous recessive for the trait CYSTIC FIBROSIS -Affects the mucus-producing glands, digestive enzymes, and sweat glands ALBINISM -Caused by altered genes, resulting in the absence of melanin in hair and eyes TAY-SACHS DISEASE -Gangliosides (fatty acids) accumulate in the brain, inflating brain nerve cells and causing mental deterioration GALACTOSEMIA -Recssive genetic disorder characterized by the inability of the body to digest galactose DOMINANT GENETIC DISORDERS -Huntington's Disease affects the nervous system -Achondroplasia is a genetic condition that causes small body size and limbs that are comparatively short

Big Idea 1: The process of evolution drives the diversity and unity of life Enduring Understanding 1.A- Change in the genetic makeup of a population over time is evolution Essential knowledge 1.A.1: Natural selection is a major mechanism of evolution According to Darwin's theory of natural selection, competition for limited resources results in differential survival. Individuals with more favorable phenotypes are more likely to survive and produce more offspring thus passing traits to subsequent generation. (Fitness) Evolutionary fitness is measured by reproductive success Genetic variation and mutation play roles in natural selection. A diverse gene pool is important for the survival of a species in a changing environment.

AP Biology Summer Assignment Unit 1: Ecology and the Biosphere Ch. 50-55 ? Ecology is the study of interactions between organisms and the environment. These interactions are critical to keeping us alive. Look through each chapter and list the single concept within each chapter that you think is the most important concept in the chapter.

AP Biology Chapter 21 Genomes and Their Evolution Overview ? Reading the Leaves form the Tree of Life Scientists are now able to compare different species by comparing their DNA We have sequenced the full DNA of many different species now By comparing, we can: study the set of genes that control group defining characteristics Learn about the long evolutionary history of shared ancient genes and their products (by looking at the genome of more different species such as bacteria, fungi, etcs and comparing to animals/humans.) Genomics: The study of whole sets of genes and their interactions. Bioinformatics: a new field ? the application of computational methods to the storage and analysis of biological data.

Campbell's Biology, 9e (Reece et al.) Chapter 1 Introduction: Themes in the Study of Life This introductory chapter explores the basic themes and concepts of biology, with emphasis on the core theme of evolution. It also introduces students to the thinking of scientists. Questions are therefore general; however, an effort has been made to include some from each skill level. As in the rest of this test bank, questions that feature art or those for which several questions follow upon some data or a scenario are placed together at the end of the chapter. Multiple-Choice Questions 1) A localized group of organisms that belong to the same species is called a A) biosystem. B) community. C) population. D) ecosystem. E) family. Answer: C Topic: Concept 1.1

Introduction to genetics

Chapter 14 Mendel and the Gene Idea Lecture Outline Overview: Drawing from the Deck of Genes The ?blending? hypothesis popular 1800s This hypothesis proposes that genetic material contributed by each parent mixes in a manner analogous to the way blue and yellow paints blend to make green. With blending inheritance, a freely mating population will eventually give rise to a uniform population of individuals. Everyday observations and the results of breeding experiments tell us that heritable traits do not blend to become uniform. An alternative model: the ?particulate? inheritance proposes that parents pass on discrete heritable units, genes, that retain their separate identities in offspring. Genes can be sorted and passed on, generation after generation, in undiluted form.
