A non-reciprocal recombination process that results in an alteration of the sequence of a gene to that of its homologue.
The non-reciprocal exchange of sequence.
An genetic event that produces abnormal segregations by non-reciprocal recombination. Gene conversion has been extensively studied in ascomycetes, where it occurs following meiosis as the result of the formation of a mismatched base pair and subseque nt repair by the mismatch repair system.
A non-reciprocal process in which a gene is replaced by its homologue during meiosis. This is detectable in Neurospora crassa as 6:2 or 5:3 distorted genotypic ratios of ascospores in individual asci.
A nonreciprocal recombination process resulting in a sequence becoming identical with another.
The asymmetrical segregation of genes during replication that leads to an apparent conversion of one gene into another.
A process that results in the four haploid products of meiosis displaying an unusual segregation pattern.
The transfer of DNA sequences between two very similar genes, most often by unequal crossing over during meiosis; can be a mechanism for mutation if the transfer of material disrupts the coding sequence of the gene or if the transferred material itself contains one or more mutations Related Terms: pseudogene ; recombination ; unequal crossing over
A meiotic process of directed change in which one allele directs the conversion of a partner allele into its own form.
Gene conversion is a phenomenon which occurs during meiotic division. It is a process by which DNA sequence information is transferred from one DNA helix (which remains unchanged) to another DNA helix, whose sequence is altered. It occurs occasionally during general recombination.
