The Science of Heredity
Chapter 5: Genetics- The Science of Heredity
Organisms produced by sexual reproduction inherit half their DNA from each parent. The new combination of DNA determines an organism's traits.
- What controls the inheritance of traits in organisms?
- What is the probability and how does it help explain the results of genetic crosses?
- What role do chromosomes play in inheritance?
- What forms the genetic code?
- Mendel's Work
- Probability and Heredity
- The Cell and Inheritance
- Genes, DNA and Proteins
Chapter 6: Modern Genetics
A person's traits depend on which alleles are inherited from each parent, how those alleles work together, and environmental factors.
- What are some patterns of inheritance in humans?
- How do geneticists trace the inheritance of traits?
- What are three ways of producing organisms with desired traits?
- Human Inheritance
- Human Genetic Disorders
- Advances in Genetics

Chapter 8: Earth's History
Evidence from rocks shows that life has existed for billions of years and how Earth has changed over time.
- How do geologists determine the relative age of rocks?
