recombination etymology

Etymology:

• Re- ("again") + combine ("to unite")

Meaning:

Recombination refers to the process of genetic reshuffling that occurs during meiosis, the cell division that produces gametes (eggs and sperm). During recombination, homologous chromosomes exchange genetic material, creating new combinations of alleles.

Origin:

The term "recombination" was first used in the early 1900s by geneticist Thomas Hunt Morgan and his team to describe the breaking and rejoining of chromosomes during meiosis. Morgan's work on fruit flies provided evidence for the role of genetic recombination in inheritance and variation.

Historical Context:

• Before the 1900s: The theory of inheritance was based on the idea of blending, where offspring inherited a mix of traits from both parents.
• Early 1900s: Morgan's experiments with fruit flies showed that traits were inherited in discrete units called genes, and that recombination during meiosis shuffled these genes to create genetic diversity.
• Modern Genetics: The understanding of recombination has been expanded through the study of molecular genetics and DNA technology, which has revealed the precise mechanisms of gene exchange during meiosis.
