Editing Genetic recombination (section)

==Gene conversion==
{{main|Gene conversion}}
In gene conversion, a section of genetic material is copied from one chromosome to another, without the donating chromosome being changed. Gene conversion occurs at high frequency at the actual site of the recombination event during [[meiosis]]. It is a process by which a DNA sequence is copied from one [[Nucleic acid double helix|DNA helix]] (which remains unchanged) to another DNA helix, whose sequence is altered. Gene conversion has often been studied in fungal crosses<ref>{{cite book | vauthors = Stacey KA | date = 1994 | chapter = Recombination | veditors = Kendrew J, Lawrence E | title = The Encyclopedia of Molecular Biology | location = Oxford | publisher = Blackwell Science | pages = 945–950 }}</ref> where the 4 products of individual meioses can be conveniently observed. Gene conversion events can be distinguished as deviations in an individual meiosis from the normal 2:2 segregation pattern (e.g. a 3:1 pattern).
