What is the most significant role of homologous recombination in eukaryotes that is not found in prokaryotes? exchange of genetic information between parental chromosomes DNA repair gene conversion generation of heteroduplex DNA

The correct answer is "exchange of genetic information between parental chromosomes".

Explanation:

Homologous recombination is a genetic recombination that occurs when two similar or identical molecules of DNA exchange some of its nucleotide sequences. This type of recombination is most widely used for DNA repair purposes, however this is not distinctive of eukaryotes as prokaryotes use it as well. Therefore the most significant an unique role of homologous recombination in eukaryotes is the exchange of genetic information between parental chromosomes. This particular function is known as chromosomal crossover and it is only found in eukaryotes.
