<unk>  is a rare type of genetic recombination that may occur in some types of somatic cells during mitosis.<unk>  may occur in organisms that do not have a cycle of sexual reproduction where chromosomal<unk>  would normally occur during meiosis to generate genetic variation. It can only occur in diploid cells and a pair of chromosomes is required for the<unk>  to occur.
The<unk>  results in the production of homozygous allele combinations in all heterozygous genes that are located on that chromosome arm distal to the<unk> . Thus when a<unk>  occurs, genes that were previously recessive are expressed creating a new phenotype.<unk>  is known to occur in some asexually reproducing fungi and in normal human cells, where the event may allow normally recessive cancer-causing genes to be expressed and thus predispose the individual to the development of cancer.
