Final answer:
Genetic recombination occurs through crossing over during meiosis, which reduces linkage disequilibrium and increases genetic diversity.
Step-by-step explanation:
Genetic recombination is the process that reduces linkage disequilibrium by breaking up overrepresented haplotypes and creating new ones. It occurs during meiosis through a process called crossing over. During crossing over, genetic material is exchanged between non-sister chromatids of homologous chromosomes, creating unique combinations of genes and reducing the linkage between specific alleles.
