The most probable fate of a du- plicate gene copy is pseudogenization (Ohno 1972) and that hence the majority of duplicate gene copies are eventually lost from the genome

Gene duplication may occur through unequal crossing-over of duplicated chromosomes harboring the gene during meiotic cell divisions in the germ line. This recombination is mediated by, for example, homologous retrotransposable elements that fl ank the gene.
