    1. The Influence of Heredity on Development

    2. Heredity and Genetics Heredity Ones nature based on biological transmission of traits and characteristics Genetics Field within the science of biology that studies heredity Genetics Influence our Physical traits Behavioral traits Psychological problems Teaching Tip: Have students individually generate a list of characteristics they believe they inherited. Compile a class list and classify these characteristics. Are they primarily physical? Are some personality traits or temperament? Discuss how research is proving that many human characteristics are inborn.Teaching Tip: Have students individually generate a list of characteristics they believe they inherited.

    3. What Are Chromosomes and Genes? Chromosomes Found in cells 23 pairs Genes Segments of DNA within chromosomes Regulate development of traits Transmitted by single gene or may be polygenic 20,000 to 25,000 genes in every cell Technology Tip: Have students go to the website for the Human Genome Project to learn more about genetics.
