Gene redundancy is a term used in genetics to describe the presence of multiple copies of the same gene in an organism's genome. It allows for genetic resilience and flexibility in response to environmental changes. Synonyms for gene redundancy include gene duplications, multiple copies of genes, genetic redundancies, gene amplification, and gene homology. These terms are essentially interchangeable and refer to the same concept. Gene redundancy plays a crucial role in evolution, allowing for the development of new functions in organisms and the elimination of deleterious mutations. Understanding gene redundancy is important in biotechnology and medical research, as it can help identify potential drug targets and disease-causing mutations.
