The significance of genetic recombination lies in its contribution to genetic diversity, which is essential for the evolution of organisms. During sexual reproduction, genetic recombination occurs through processes like meiosis, where alleles are shuffled and exchanged. This leads to new combinations of genes in offspring, which can enhance a population's ability to adapt to changing environments, resist diseases, and survive selective pressures. By increasing genetic variation, recombination plays a vital role in the evolutionary process, influencing traits that may determine an organism's fitness.
