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.

WebApr 8, 2024 · Recombination is a phenomenon which results in the formation of an offspring with combined characteristics as a result of the separation of genetic material during crossing over (at the time of meiosis). We hope that we are able to define linkage and recombination clearly. Genetic recombination (also known as genetic reshuffling) is the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be further passed on from parents to offspring. Most recombination occurs naturally and can be classified into two types: (1) interchromosomal …
