Genetic recombination is the exchange of genetic material between different organisms. It occurs during meiosis, which is the cell division that produces gametes. During meiosis, 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. Recombination can occur between the paired chromosomes inherited from each of one's parents. During the alignment, the arms of the chromosomes can overlap and temporarily fuse, causing a crossover. Recombination can also occur between... Show more Genetic recombination is the exchange of genetic material between different organisms.
