Clonal interference
Clonal interference is a phenomenon in evolutionary biology, related to the population genetics of organisms with significant linkage disequilibrium, especially asexually reproducing organisms. The idea of clonal interference was introduced by A ...
, a phenomenon that occurs when two (or more) beneficial mutations arise independently in different individuals in a genetically homogeneous population of an asexually reproducing organism
*
Aggregating anemone
The aggregating anemone (''Anthopleura elegantissima''), or clonal anemone, is the most abundant species of sea anemone found on rocky, tide swept shores along the Pacific coast of North America. This cnidarian hosts endosymbiotic algae called z ...
, also called clonal anemone

Vegetative cloning
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specializ ...
, a form of asexual reproduction in plants
*
Clonal reproduction
Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without ...
Immunology

Clonal deletion
In immunology, clonal deletion is the process of removing T and B lymphocytes from the immune system repertoire. The process of clonal deletion helps prevent recognition and destruction of the self host cells, making it a type of Negative selecti ...
, a process by which B cells and T cells are deactivated before act significantly upon specific antigens
*
Clonal selection
In immunology, clonal selection theory explains the functions of cells of the immune system (lymphocytes) in response to specific antigens invading the body. The concept was introduced by Australian doctor Frank Macfarlane Burnet in 1957, in an ...
theory, a model for how the immune system responds to infection
*Clonal
anergy
In immunology, anergy characterizes the absence of a response from the body's defense mechanisms when confronted with foreign substances. This phenomenon involves the direct induction of peripheral lymphocyte tolerance. When an individual is i ...
, a lack of reaction by the body's defense mechanisms to foreign substance

Clone (genetics)
Molecular cloning is a set of experimental methods in molecular biology that are used to assemble recombinant DNA molecules and to direct their replication within host organisms. The use of the word ''cloning'' refers to the fact that the metho ...
