👉 The gene fluid, also known as genetic fluidity or genetic recombination, is a biological process that describes the exchange and mixing of genetic material between different genes or chromosomes during meiosis, the cell division process that produces gametes (sperm and egg cells). This fluidity allows for the creation of unique combinations of alleles (different forms of a gene) in offspring, increasing genetic diversity within a population. It's a key mechanism in evolution, as it enables beneficial traits to spread more rapidly through populations by shuffling genetic information, thus enhancing adaptability and resilience to environmental changes.
