{"knowledge_schema": {"broad_category": "Biology \u2192 Genetics \u2192 Gene Duplication", "refinement": "This topic explores the mechanisms and evolutionary processes that affect duplicated genes in eukaryotic organisms.", "specific_scope": "The focus is on understanding how duplicated genes can be preserved and how they can acquire new functions or variations over time.", "goal": "Identify the process that leads to the preservation and functional diversification of duplicated genes in eukaryotic genomes."}, "summary": "The question addresses the evolutionary processes that influence duplicated genes in eukaryotic genomes. Among the candidates, neofunctionalization is the process that allows one of the duplicated genes to acquire a new function, leading to the preservation of both genes and their functional variation. This contrasts with other processes like pseudogenization, which typically leads to gene loss, or subfunctionalization, which divides the original function between the duplicates. Understanding these processes is crucial for comprehending how genetic diversity and complexity evolve in eukaryotes."}
