In other words, it can tell you if you will or will not. Khan academy is a 501(c)(3) nonprofit organization. This diagram helps to identify the probability of an offspring having specific genotypes and characteristics after the breeding process. Punnett squares are a simple tool for students to create that will organize their data and provide a visual although punnett squares are useful tools to predict outcomes, many students view them as riddles.
