WebAboutTranscript. Genetic recombination is a process that occurs during meiosis, which is the type of cell division that produces gametes. 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. WebGenetic recombination is a programmed feature of meiosis in most sexual organisms, where it ensures the proper segregation of chromosomes. Because the frequency of recombination is approximately proportional to the physical distance between markers, it provides the basis for genetic mapping.
