GENETIC RECOMBINATIONS Meaning and
Definition
-
Genetic recombination refers to the process by which DNA molecules exchange genetic information, resulting in the formation of new combinations of genes. It occurs during sexual reproduction and is a crucial mechanism for the generation of genetic diversity and evolution. This process involves the breaking and rejoining of DNA strands, leading to the exchange of genetic material between homologous chromosomes.
Genetic recombination occurs in multiple ways. One common process is called crossing over, which takes place during meiosis when homologous chromosomes pair up. Small segments of DNA are exchanged between these paired chromosomes, resulting in the recombination of genetic material. This creates new combinations of genes on the chromosomes passed on to offspring.
Another mechanism of genetic recombination is non-crossover recombination. In this process, DNA strands are broken and rejoined without any exchange of genetic material between chromosomes. It can occur during both meiosis and mitosis, leading to genetic diversity among cells and individuals.
Genetic recombination plays a vital role in increasing the genetic variation within a population. It allows for the shuffling and mixing of genes, enabling organisms to respond to changing environments, adapt, and potentially acquire advantageous traits. This process also facilitates the repair of damaged DNA and the elimination of harmful mutations through the exchange of genetic information.
Overall, genetic recombination is a fundamental biological process that contributes to genetic diversity, adaptation, and evolution.

Etymology of GENETIC RECOMBINATIONS
The word "genetic" is derived from the Latin word "geneticus", which means "pertaining to birth or origin". It is derived from the Latin word "genus", meaning "origin" or "race".
The term "recombination" is derived from the Latin word "recombinare", which means "to combine again". It is composed of the prefix "re-" meaning "again" and the verb "combinare" meaning "to combine".
When these two terms are combined, "genetic recombinations" refer to the process of combining genetic material or genes to produce offspring with new combinations of genes.
