Genetic redundancy
Genetic Redundancy
Genetic redundancy (/dʒɪˈnɛtɪk rɪˈdʌndənsi/) is a phenomenon in genetics where a set of genes share overlapping functions. This means that the loss of one gene can be compensated by the function of another gene, thus ensuring the survival and normal functioning of an organism.
Etymology
The term "genetic redundancy" is derived from the field of genetics, which studies the hereditary material in living organisms, and the term "redundancy", which refers to the state of being not strictly necessary to functioning.
