What is "phylogenomics"

n. (context genetics English) The science that studies the relationship of the function of genes to their evolution

Phylogenomics is the intersection of the fields of evolution and genomics. The term has been used in multiple ways to refer to analysis that involves genome data and evolutionary reconstructions. It is a group of techniques within the larger fields of phylogenetics and genomics. Phylogenomics draws information by comparing entire genomes, or at least large portions of genomes. Phylogenetics compares and analyzes the sequences of single genes, or a small number of genes, as well as many other types of data. Four major areas fall under phylogenomics:

• Prediction of gene function
• Establishment and clarification of evolutionary relationships
• Gene family evolution
• Prediction and retracing lateral gene transfer.
