This work analyzes the difficulties encountered in teaching the "Population Genetics" module at qualifying secondary level. Situated at the crossroads of Mendelian genetics and evolutionary theory, this module presents a high degree of conceptual and epistemological complexity. Through an approach combining bibliographical analysis and didactic study of the Moroccan textbooks "Le nouveau dans les SVT" and " l'accueil des SVT", the research highlights shortcomings in the transposition of scientific knowledge: historical decontextualization, unbalanced use of biological examples, poor integration of the evolutionary dimension and persistent conceptual confusion. The study recommends a revision of textbooks, better historical and scientific contextualization, and ongoing teacher training to reinforce the coherence between learned and taught knowledge.
