Describe Genetic Recombination ?

Genetic recombination, which provides the variation necessary for evolution, can occur through a variety of processes during cell reproduction: deletion, or accidental loss of chromosome sections; duplications, where portions of homologous chromosomes become attached to a homologue, resulting in duplicated genes; crossovers, exchange of segments of homologous chromosomes that occurs during prophase I of meiosis; inversions, segments that are in reverse order with respect to the rest of the chromosome; and translocations, in which a piece of a chromosome may become attached to another chromosome.
