Homologous recombination is that which we are taught about in introductory biology class. It is the crossing-over process observed during meiosis, though it occurs in bacteria as well. The process involves pairing up of similar DNA sequences, with then one sequence replacing the other, or indeed for meiotic crossing over, with the generation of now two recombinant strands, one for each chromosome homolog, rather than just one. In either case, key is that it is DNA that is highly similar in terms of DNA sequence that is being either replaced or swapped. This allows for a replacement of alleles following horizontal gene transfer, or allele swapping... 2, record 1, English, - homologous%20recombination

The theory that crossing-over between nonsister chromatids results in chiasma formation. Chiasmata are thought to be the visible signs of recombination(crossing over). They appear during the diplotene stage and move toward the ends of the chromatids(a process called terminalization) ;the homologous chromosomes then separate. 3, record 2, English, - chiasmatype%20theory
