In addition to its relevance within genetic knowledge, this diagram is part of the high school curriculum, and students often confuse the symbols, which complicates understanding of the subject. Therefore, this study aimed to provide educational experiences in constructing pedigrees using cookies of different colors and shapes. The activity was conducted both in-person and remotely, involving students from integrated technical high school programs and undergraduate students in General Genetics. In all cases, the theme was explained and the activity was detailed, with each participant receiving an activity card. In the in-person format, groups of approximately five students were formed. They received square and circular cookies in dark (chocolate) and light (milk) colors, as well as rectangular wafer cookies. In the remote format, students made variations of the suggested cookie choices. Each activity card had four steps: 1. Constructing the pedigree according to the text, where square cookies represented males and circular cookies represented females. The dark (chocolate) or light (milk) colors of the cookies represented individuals affected by a certain trait (dark) or unaffected (light). Wafer cookies were used to connect individuals, either through marriage or descent. 2. Identifying the type of inheritance, with colors aiding in recognizing dominant inheritance patterns when affected parents had normal offspring, and recessive inheritance when normal parents had affected offspring. 3. Identifying the genotypes of all individuals in the pedigree as homozygous recessive, heterozygous, or unknown genotype. 4. Inferring genetic counseling, referring to calculations used in Mendel's First Law. Through this hands-on practice, students correctly understood and used pedigree symbols. This approach proved effective in creating strategies that stimulate students' scientific thinking and facilitated understanding of concepts related to heredity, genealogical tree production, and genetic counseling.ptCiências BiológicasHeredogramaGenética - EnsinoGenealogiaAconselhamento genéticoRecessivo e dominante - HerançaTeaching GeneticsRecessive and Dominant InheritanceGenealogyGenetic CounselingHeredograma: utilização de biscoitos e bolachas como facilitadores de simbologiaTrabalho de Conclusão de CursoCIENCIAS BIOLOGICAS
