These squares are a way to predict the possible genetic outcomes of the offspring when two individuals with known genotypes are crossed.
The Punnett Square is named after British geneticist Reginald Punnett and is commonly used in biology to understand inheritance patterns.
Each square effectively represents a possible combination of traits that their offspring could inherit. It’s a simple way to visualise the probabilities of different traits showing up in the offspring.
A Punnett Square is a useful tool that helps predict the variations and probabilities resulting from cross-breeding.
It is often used to study the outcomes of cross-breeding but it can also be used to understand the genetic traits in the offspring of animals, including humans.
