What is the name of the diagram showing the gene combinations that might result from a genetic cross?

The diagram that shows the possible gene combinations resulting from a genetic cross is known as a Punnett Square. This tool is extensively used in genetics to predict the genotypic and phenotypic ratios of offspring from particular parent crosses.

In a Punnett Square, the alleles from one parent are displayed along the top, while the alleles from the other parent are listed along the side. By filling in the boxes within the square, you can visually represent the potential genetic outcomes for the offspring, thereby understanding how certain traits may be inherited. This method effectively demonstrates the principles of Mendelian inheritance, showing how dominant and recessive alleles can combine to create various traits.

Other options such as a Phenotype Chart, Allele Map, and Genotype Grid are not standard terms used for depicting the outcomes of genetic crosses. They may refer to other concepts in genetics but do not serve the specific purpose of illustrating the expected inheritance patterns stemming from a cross, which is the primary function of a Punnett Square.
