Introduction to Heredity, Genetics, and Evolutionary Biology

How do traits pass from one generation to the next, and how do species adapt over millions of years? Understanding the mechanisms of heredity and evolution is fundamental to grasping how life on Earth functions and changes. This written course guides you through the foundational concepts of genetics and evolutionary biology. You will transition from learning basic terminology to understanding complex inheritance patterns and evolutionary mechanisms, preparing you for academic exams or a deeper appreciation of biological sciences. What you'll learn: Learn the laws of Mendelian genetics and how dominant and recessive traits are inherited; Understand the structure and function of DNA, genes, chromosomes, and sex determination; Describe the processes of natural selection, speciation, and evolutionary adaptation; Practice solving monohybrid and dihybrid crosses using Punnett squares; Explore modern concepts in genetics including basic gene-editing technologies and epigenetics; Trace the evolutionary relationships between different organisms using fossil evidence and anatomical structures. The course begins with essential terminology and the laws of inheritance before moving into the molecular basis of genetics and the evidence supporting evolution. You will progress step-by-step through clear written explanations, practical examples, and self-assessment exercises. This course is designed for beginners, high school biology students preparing for exams, or anyone seeking a solid foundation in life sciences. No prior knowledge of genetics is required.
