  4. Tips for Doing Well Read the chapters. Do not fall behind. Make a glossary of bold-face terms in each chapter, and learn their definitions. Work the assigned problems and work through the problems, discussion questions, and “Insights and Solutions” sections at the end of each chapter.

  5. I. Introduction to Genetics A. What is genetics? “Genetics” is the branch of biology concerned with heredity and variation What is heredity? What is variation?

  6. Why Should You CareAbout Genetics? Genetics is going toplay an increasingly important role in your life

  7. Genetics in the News Forensic Genetics

  8. Genetics in the News What rights do we have to not divulge information contained in our genes?

  9. Genetics in the News Genetic discrimination Genetic discrimination describes the differential treatment of individuals or their relatives based on their actual or presumed genetic differences as distinguished from discrimination based on having symptoms of a genetic-based disease Denial of health insurance Difficulty finding employment

  10. Genetics in the News Other issues Genetic engineering of foods Human cloning Stem cell research

  11. I. Introduction to Genetics B. History of Genetics Prehistoric Times: Domesticated Animals and Cultivated Plants The Greek Influence (500 - 300 B.C.) Hippocrates treatise On the Seed inheritance of acquired traits Aristotle 1600 - 1850 The Dawn of Modern Biology 1600s - preformation - sex cells contain a complete miniature adult called the homunculus “Early”

  12. Depiction of the “homunculus,” a sperm containing a miniature adult, perfect in proportion, and fully formed. (Hartsoeker, N. Essay de dioptrique, Paris, 1694, p. 230)

  13. I. Introduction to Genetics B. History of Genetics 1600 - 1850 The Dawn of Modern Biology 1600s - preformation - sex cells contain a complete miniature adult called the homunculus. Popular well into 1700s. 1600s - William Harvey (1578 - 1657) is credited with the theory of epigenesis, that an organism is derived from substances present in the egg. 1800s - Idea of spontaneous generation disproved, but a commonly held belief was the fixity of species, the idea that all species remain unchanged in form from the moment of their appearance on Earth. 1859 - Charles Darwin published On the Origin of Species, in which he proposed natural selection, the theory that organisms with heritable traits that allow them to adapt to their environment are better able to survive and reproduce than those with less adaptive traits.

  14. I. Introduction to Genetics B. History of Genetics The primary gap in Darwin’s theory was a lack of understanding of the genetic basis of variation and inheritance. Gregor Johann Mendel conducted experiments between 1856 and 1863 that served as the basis for the chromosomal theory of inheritance, which states that inherited traits are controlled by genes that reside on chromosomes.

  15. I. Introduction to Genetics B. History of Genetics The dark side of genetics Eugenics - subjecting human characteristics to artificial selection to “improve” the human race. Positive eugenics - encouraged parents displaying favorable characteristics (e.g. superior intelligence, intellectual achievement, and artistic talent) to have large families Negative eugenics - restricting the reproduction of parents displaying unfavorable characteristics (e.g. low intelligence, mental retardation, and criminal behavior).

  16. I. Introduction to Genetics B. History of Genetics Eugenics was very popular in the United States, with over half of the states having laws that required the sterilization of those considered “genetically inferior.” Sterilization programs continued in the United States into the 1940s. Hitler’s Nazi Germany in the 1930s was an extension of the eugenics movement. Euphenics is a modern term that refers to medical or genetic intervention designed to reduce the impact of defective genotypes on individuals.
