Final answer:
DNA from different sources forming a double-stranded region is associated with the process of hybridization. Genetic recombination, separate from this, involves crossing over during meiosis.
Step-by-step explanation:
The DNA from one source forms a double-stranded region with the DNA from another source during the process of hybridization. This is distinct from genetic recombination, which is a different biological process. Genetic recombination occurs through the process of crossing over during meiosis. This involves the exchange of genetic material between non-sister chromatids of homologous chromosomes, leading to the formation of new combinations of alleles and contributing to genetic variation in offspring.
