This educational video provides a comprehensive guide to understanding and analyzing pedigrees in the context of high school biology genetics. Using the model organism Drosophila melanogaster (fruit flies), the host explains how to interpret family tree diagrams to track the inheritance of specific traits through multiple generations. The lesson covers foundational concepts such as pedigree symbols, differentiating between wild-type and mutant traits, and the definitions of dominant, recessive, autosomal, and sex-linked inheritance.
