Punnett squares are a simple and visual tool used in genetics to predict the probability of offspring inheriting certain traits from their parents. This tool is named after Reginald Punnett, a British geneticist who first introduced it in the early 20th century. Punnett squares are commonly used to study Mendelian inheritance patterns, where genes are passed down from parents to offspring in predictable ways.
When using a Punnett square, the alleles (different forms of a gene) from each parent are represented along the top and side of a square grid. By combining the alleles in the squares, you can determine the possible genotypes and phenotypes of the offspring. This allows scientists and students to understand the inheritance of traits such as eye color, hair texture, and genetic disorders.
