Course Outline
Course Description
This course explores how genetic information is stored, inherited, and expressed in living organisms. Students will investigate the structure and function of DNA, genes, and chromosomes, examine the processes of cell division and reproduction, and learn how traits are passed from one generation to the next. As the course progresses, students will explore increasingly complex patterns of inheritance and discover how modern biotechnology is transforming medicine, agriculture, and forensic science. Through scientific investigations, real-world case studies, and problem-solving activities, students will develop a strong foundation in genetics and an appreciation for its role in modern society.
Unit 1: DNA, Genes, and Chromosomes
Overview
Students are introduced to the molecular basis of inheritance. They will learn how DNA stores genetic information, how genes influence traits, and how chromosomes organize hereditary information within cells.
Subtopics
- What Is DNA?
- Genes and Their Functions
- Chromosomes
- Genome and Genetic Information
- DNA Structure and Replication
Key Skills
- Identifying structures involved in inheritance
- Relating DNA, genes, and chromosomes
- Interpreting genetic information
- Understanding DNA replication
Unit 2: Cell Division and Reproduction
Overview
Students examine how cells reproduce and how genetic information is transmitted during reproduction. They will compare asexual and sexual reproduction and investigate the processes of mitosis and meiosis.
Subtopics
- Asexual Reproduction
- Sexual Reproduction
- Mitosis
- Meiosis
- Comparing Mitosis and Meiosis
Key Skills
- Comparing reproductive strategies
- Interpreting cell division diagrams
- Explaining genetic variation
- Analyzing chromosome behavior
Unit 3: Inheritance Patterns
Overview
Students learn the principles of inheritance and use genetic models to predict the transmission of traits. They will explore alleles, dominant and recessive inheritance, and the use of Punnett squares.
Subtopics
- Traits and Variation
- Alleles and Gene Pairs
- Dominant and Recessive Inheritance
- Punnett Squares
- Predicting Inheritance
Key Skills
- Using genetic notation
- Constructing Punnett squares
- Predicting inheritance outcomes
- Analyzing genetic probabilities
Unit 4: Complex Genetics
Overview
Students investigate inheritance patterns that extend beyond simple Mendelian genetics. Topics include codominance, sex-linked inheritance, blood groups, polygenic traits, and genetic disorders.
Subtopics
- Codominance and Incomplete Dominance
- Sex Determination and Sex-Linked Traits
- Multiple Alleles and Blood Groups
- Polygenic Inheritance
- Genetic Disorders
Key Skills
- Analyzing complex inheritance patterns
- Solving advanced genetics problems
- Interpreting pedigrees and family histories
- Evaluating genetic evidence
Unit 5: Modern Genetics and Biotechnology
Overview
Students explore modern applications of genetics and biotechnology. They will examine genetic engineering, DNA profiling, cloning, gene therapy, and the ethical issues associated with these technologies.
Subtopics
- Genetic Engineering
- DNA Profiling
- Cloning
- Gene Therapy
- Ethical Issues in Genetics
Key Skills
- Evaluating biotechnology applications
- Interpreting DNA evidence
- Assessing scientific claims
- Considering ethical implications of genetic technologies
Course Outcomes
By the end of this course, students will be able to:
- Explain how DNA stores and transmits genetic information.
- Describe the roles of genes and chromosomes in inheritance.
- Compare mitosis and meiosis and explain their importance.
- Predict inheritance patterns using genetic models.
- Analyze complex forms of inheritance.
- Evaluate the benefits and risks of modern genetic technologies.
