What tool is commonly used to predict the outcome of genetic traits?

A Punnett square is a graphical representation used to predict the genotypes and phenotypes of offspring from parental genetics. It organizes the possible combinations of alleles that the offspring could inherit from each parent, making it easy to visualize the potential genetic makeup resulting from a cross. This tool is particularly effective for simple inheritance patterns, such as Mendelian traits, where dominant and recessive alleles can be clearly identified.

In contrast, while genetic maps provide valuable information about the location of genes on chromosomes, they do not directly predict trait outcomes. The Fibonacci sequence is a mathematical concept unrelated to genetics, and chromatography is an analytical technique used for separating mixtures rather than predicting genetic traits. Therefore, the use of Punnett squares is the most appropriate method for anticipating genetic outcomes, making it the correct choice.
