Biologia e Genética de Leo (often abbreviated simply as “Leo”) is a widely used Portuguese‑language textbook that integrates fundamental concepts of cell biology, molecular genetics, and organismal biology. This paper presents a concise but comprehensive review of the book’s structure, pedagogical features, and scientific content, with particular emphasis on its treatment of classical and modern genetics. The analysis is based on a systematic examination of the publicly available table of contents, sample chapters, and reviews from academic forums. Strengths (clear language, extensive illustrations, problem sets) and limitations (limited coverage of recent CRISPR technologies, occasional outdated references) are discussed. Recommendations for instructors and students who seek a free, legally‑obtained digital copy are provided, together with suggestions for complementary open‑access resources that can update the material.
