A Punnett square is a diagram that is used to predict the possible genotypes of offspring in a genetic cross. The Punnett square is named after Reginald Punnett, who first described it in 1905. Punnett squares are used by geneticists to predict the probability of inheriting a particular trait. The worksheet answers provide students with practice in using Punnett squares to solve genetics problems.
Punnett squares are an important tool for geneticists because they allow them to predict the probability of inheriting a particular trait. This information can be used to make decisions about breeding programs or to identify individuals who are at risk for developing a genetic disorder. Punnett squares are also used in genetic counseling to help families understand the risks of passing on genetic disorders to their children.
