PowerPoint Presentation: “Genes and Traits” c. o Use two Punnett squares to model each trait independently, then multiply the probabilities to find the probability of a given allele combination. Image of a Punnett Square Your prediction is that (74%) of the offspring would have the dominant phenotype, and (25%) of the offspring would have the recessive phenotype. At the station there are plastic Easter eggs. A Punnett square is a grid system that can be set up and used to predict the possible outcomes that may result from the mating process between two individuals, when their genotypes are known. Tutorial to help answer the question. INTRODUCTION Punnett squares and pedigrees are tools used to visualize patterns of inheritance, as well as to make predictions of the probability of inheriting a particular trait, disease, or disorder. In this activity, students conduct a probability experiment representing traits that would occur in subsequent generations of a fictional flower. [Filename: punnett1. Download: Lab.
