Introduction to Genetics: Principles of Inheritance and Variation

Understanding how traits are passed down through generations is fundamental to biology, yet genetic mechanisms can often feel complex and overwhelming. This text-only course breaks down the core principles of inheritance and variation into clear, structured explanations, taking you from basic Mendelian laws to modern genetic concepts. Read through detailed breakdowns of genetic crosses, chromosomal inheritance, and real-world genetic phenomena. What you'll learn: Understand Mendel's laws of inheritance and how traits are transmitted across generations; Analyze monohybrid and dihybrid crosses using Punnett squares; Explore deviations from Mendelian genetics, including codominance and incomplete dominance; Examine chromosome theory, sex determination, and common genetic disorders; Learn about modern genomic variations and foundational concepts of gene-editing technologies. The course begins with essential terminology and historical experiments before guiding you step-by-step through genetic mapping, pedigree analysis, and modern molecular applications. This course is designed for beginners, biology students, and anyone looking to build a strong scientific foundation in genetics without any prior advanced knowledge.
