Single Strand Exchange Recombination: According to Mesclson and Radding, a single strand break in one of the two homolgous DNA molecules is quite common. The free end of the broken strand invades the unbroken double helix and displaces one strand.

During this process, homologous chromosomes pair up and form a unit called a tetrad. The chromosomes can then cross over and exchange genetic material, which results in new combinations of alleles.
