Despite the relevance of the data, they were only accepted by the scientific community in the 20th century, in what was called Mendel's Rediscoveries. Reginald Punnett was a scientist during this period, and proposed a diagram to help solve intersections. The didactic way of separating parental gametes and joining them during fertilization made it widely used. The Punnett square, as it became known, is a basic content within genetics, covered in elementary, secondary and higher education. In this context, the present work aims to produce, apply and evaluate the GeneCruzing game on Mendelian Inheritance and Punnett square at the Instituto Federal de Alagoas, Campus Maceió, in high school and in the General Genetics discipline of the Bachelor's degree in Biological Sciences. The game was built with low-cost materials: Two dice, one with genotypes AA (1 sided), Aa (3 sides) and aa (2 sides), and the other BB (1 sided), Bb (3 sides) and bb (2 sides), cardboard and rubberized (E.V.A.) with 30 cm2; Four rubberized Punnett squares of different colors (green, yellow, blue and red) measuring 40 x 47.5 cm; Gamete letters on paper AB, Ab, aB and ab, measuring 7 x 8.5 cm; Paper genotype cards 1 AABB, 2 AABb, 1 AAbb, 2 AaBB, 4 AaBb, 2 Aabb, 1 aaBB, 2 aaBb, 1 aabb, measuring 3.5 x 10 cm; 10 questions with second law Mendelian crosses. Before and after the game, a questionnaire on the topic was filled out. The room was divided into up to four teams, and each received a Punnett square, gamete cards, genotype cards, a question and a timer. Each team rolled the die twice for the parental genotypes and then started timing the timer. The table was filled out, the question was answered and the timer was stopped for the mediator to evaluate. When correct, a new question was delivered and the dice were rolled again. The team that completed the greatest number of questions in the shortest time will be the winner. Students were motivated and engaged with GeneCruzing. In approximately 10 minutes, 4 questions were resolved. The questionnaire answered before, with an average of 10% correct, rose after the game to 60% correct, showing the improvement in learning. In this sense, the GeneCruzing game stands out as a teaching alternative with an educational and playful tool, providing better assimilation of basic genetic concepts, and especially crossings from the perspectives of Mendel's Laws.ptCiências biológicasGenética - Ensino-aprendizagemJogos educativosGameficaçãoLei de MendelQuadro de PunnetTeaching-learning in GeneticsEducational gamesMendel's lawTrabalho de Conclusão de CursoCIENCIAS BIOLOGICAS
