A pedigree chart is a visual representation used primarily to track a genetic trait through multiple generations within a family. This tool allows healthcare professionals and geneticists to illustrate how a specific trait or genetic condition is passed down by tracing the lineage and relationships between individuals. By doing so, it helps in identifying patterns of inheritance, such as autosomal dominant or recessive traits, and can assist in assessing the likelihood of individuals inheriting or passing on specific genetic conditions.

The other choices, while related to genetics, serve different purposes. Assessing gene mutations involves analyzing DNA sequences and is not the primary function of a pedigree chart. Similarly, determining phenotype variations relates to studying the physical expression of genes within a population, focusing on their diversity rather than family lineage. Lastly, chromosome structure analysis deals with the physical composition of chromosomes and their arrangement, which requires different methodologies than what is provided by a pedigree chart.
