Genetic recombination

Definition

noun

The process of forming new allelic combination in offspring by exchanges between genetic materials (as exchange of DNA sequences between DNA molecules).


Supplement

This process is a natural process, such as the crossing over between homologous chromosomes during meiosis. It can also be done artificially by applying genetic engineering techniques.
