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. The process of literally cutting and pasting DNA backbones into new combinations. It is very widespread in nature. Asexual. Offspring are identical clones of their parent.
