Final answer:
Homologous recombination in eukaryotes has additional functions, including the repair of double-stranded DNA breaks and promoting genetic diversity.
Step-by-step explanation:
Homologous recombination has additional functions in eukaryotes beyond its role in meiosis. One of the additional functions is the repair of double-stranded DNA breaks. When a double-stranded break occurs, enzymes and other proteins are recruited to facilitate the repair process. Proteins such as MRX, MRN, Sae2, and Sgs1 are involved in these repair pathways. Homologous recombination is also involved in maintaining genetic diversity in species by promoting the exchange of alleles between homologous chromosomes during synapsis. This ensures that novel recombinations of variant alleles occur in sperm and eggs, leading to genetic diversity.
