GENETIC RECOMBINATION Meaning and
Definition
-
Genetic recombination is a natural process that occurs during the reproduction of organisms, involving the rearrangement of genetic material from two different sources to produce offspring with unique combinations of traits. Often referred to as genetic reshuffling, it occurs through the exchange of genetic material between two DNA molecules, resulting in the creation of a new combination of genes.
During genetic recombination, the process of crossing over takes place during meiosis, the cell division that produces gametes (eggs and sperm) in sexually reproducing organisms. In this process, homologous chromosomes pair up and exchange segments of DNA, resulting in the mixing and recombination of genetic material from both parents. This recombination produces gametes with new combinations of alleles, increasing genetic diversity within a population.
The significance of genetic recombination lies in its role in evolution. By generating new combinations of traits, it introduces genetic variation within a population, which can be acted upon by natural selection. This allows populations to adapt to changing environments and increases the chances of survival and reproduction for individuals possessing advantageous traits.
Genetic recombination can occur spontaneously or can be induced artificially through various laboratory techniques. It is a fundamental process in genetics and plays a crucial role in the evolution of species.

Etymology of GENETIC RECOMBINATION
The word "genetic" originates from the French word "génétique", which was coined by the Belgian scientist Jean-Baptiste Bouillaud in 1907. It is derived from the Greek word "genesis", meaning "origin" or "creation".
The term "recombination" comes from the Latin word "recombinare", which means "to unite again" or "to bring together". It is a combination of the prefix "re-" (meaning "again" or "back") and the verb "combinare" (meaning "to unite" or "to join together").
When these two words are combined, "genetic recombination" refers to the process whereby genetic material (such as DNA) from different sources or locations is brought together and united again, resulting in the formation of new combinations of genetic traits.
