Context: The Punnett square, named after British geneticist Reginald Punnett, is a grid used to predict the possible genetic outcomes of offspring when two individuals with known genotypes are crossed.

  • It consists of a simple grid with squares representing possible combinations of traits inherited from each parent.
  • This tool helps visualize the probabilities of different traits appearing in offspring and is commonly used in biology to understand inheritance patterns, such as dominant and recessive genes.
  • Researchers utilize Punnett squares alongside Mendelian inheritance principles to study genetic traits in offspring, including those of animals and humans.
