Essential Genetics: Principles of Inheritance

Understanding how traits pass from parent to offspring is fundamental to biology and critical for studying life sciences. This course provides a clear, systematic introduction to the core laws of heredity. By the end of this text-only course, you will have a solid grasp of classical genetics, allowing you to analyze complex crosses, understand the molecular basis of variation, and solve quantitative genetics problems with confidence. What you'll learn: * Understand the foundational experiments and laws proposed by Mendel regarding segregation and independent assortment. * Analyze complex inheritance patterns including incomplete dominance, co-dominance, multiple alleles, and polygenic inheritance. * Learn the basic structure of DNA and chromosomes and how they form the physical basis of inheritance and genetic variation. * Apply statistical and probability rules to accurately predict genotypic and phenotypic ratios in various genetic crosses. * Practice solving typical genetics problems involving linkage, crossing over, sex determination, and common genetic disorders. The course begins with key terminology and historical context before diving into Mendelian principles and their exceptions. We then explore the chromosomal theory of inheritance and practice applying these concepts through detailed written explanations and exercises. This course is designed for absolute beginners interested in biology, genetics, or preparing for introductory science programs. No prior knowledge of molecular biology or advanced math is required. Begin your journey into the fascinating world of genetics today.
