In which type of analysis would you likely compare genomic data from multiple species?

The focus of this question is on the type of analysis that involves comparing genomic data across multiple species. Genomics is the field that specifically deals with the comprehensive study of an organism's complete set of DNA, including all of its genes. This field encompasses the analysis of genetic sequences, functions, and variations, making it ideal for comparative studies that aim to understand evolutionary relationships, gene function, and the genetic basis for traits among different species.

In genomic studies, researchers examine similarities and differences in the genomes of various organisms to draw conclusions about evolutionary processes, gene conservation, and adaptation. This comparative approach can reveal significant insights into the biology of organisms and their evolutionary history.

While genetics, bioinformatics, and proteomics are all important biological fields, they do not specifically focus on the comparison of genomic data among multiple species. Genetics tends to focus on single genes and their inheritance, bioinformatics involves the use of computational tools to manage and analyze biological data but does not exclusively center on genomic comparison, and proteomics is concerned with the study of the complete set of proteins produced by an organism. Thus, genomics is the most appropriate field for the analysis described in the question.
