Breakage And Reunion in Bacterial Recombinations
Breakage and reunion can be explained with reference to a and b are the two genetic loci and a+ and b+ their alleles. During synapsis the homologous chromosomes break between a and band a+ and b+. The pieces then rejoin cross-wise producing recombinants in which one chromosome contains a and b+ and the other a+ and b loci.
The recombinant chromosome contains two pieces of parental chromosome information. Breakage and reunion type of recombination does not depend upon the synthesis of new DN A molecules. There is merely mutual transfer of DNA segments from one parental chromosome to the other
