Final answer:
Homologous recombination is a genetic recombination process in which nucleotide sequences are exchanged between two similar or identical molecules of DNA. This process occurs during meiosis and involves the alignment and exchange of genetic material between homologous chromosomes.
Step-by-step explanation:
Homologous recombination is a genetic recombination process in which nucleotide sequences are exchanged between two similar or identical molecules of DNA. This process occurs during meiosis and involves the alignment and exchange of genetic material between homologous chromosomes. Homologous chromosomes have the same genes in the same order, and during recombination, segments of these chromosomes cross over and exchange genetic material, resulting in the shuffling of alleles.
