What tool is used to identify possible allele inheritance from parents?

The Punnett square is a graphical tool that is specifically designed to predict the possible allele combinations resulting from the mating of two parents. By organizing the genotypes of the parents along the top and side of a grid, the Punnett square allows for a systematic examination of how alleles may combine in the offspring. This visual representation helps to determine the probability of inheriting specific traits based on the genetic makeup of the parents.

In contrast, a chromosome map is used primarily to show the locations of genes on chromosomes rather than to predict inheritance patterns. A dihybrid cross is a specific type of genetic cross that considers two traits at once, making it more complex than the simple predictions provided by the Punnett square. A gene tree, or phylogenetic tree, illustrates the evolutionary relationships between various biological species or entities rather than focusing on inheritance of alleles in a specific pairing.

Understanding the function of each of these tools highlights why the Punnett square is the most appropriate choice for identifying possible allele inheritance from parents.
