This implies that concerted evolution is not acting, which is corroborated by the scarcity of signatures of geneconversion and recombination. The lack of these signatures suggests a (nearly) complete absence of geneconversion. This postfertilization error may be somatic crossing-over, geneconversion mechanisms, mitotic replacement of an abnormal chromosome,26 or some other somatic event. Although we cannot fully explain their origin, two pieces of evidence suggest that these insertions occurred independently and contradict the geneconversion hypothesis. Meiotic geneconversion and crossing over: their relationship to each other and to chromosome synapsis and segregation. Second, the major effect of inversions within the inverted segment is to reduce the rate of crossing over but not that of geneconversion. The two apparently aberrant sites could differ from the others because of geneconversion or mutation that did not otherwise affect the ancestral fragment. Signatures of selection and geneconversion associated with human color vision variation. An intron-encoded protein is active in a geneconversion process that spreads an intron into a mitochondrial gene. Finally, we consider an alternative model of recombination that incorporates both crossing-over and geneconversion. We were concerned that geneconversion rather than reciprocal exchange might be occurring, which might inflate the recombination rate estimate. Incidentally, mutational sites within am were first mapped, not by any consistent inequality of recombinant flanking marker classes, but by polarity of geneconversion. Another important factor in shaping intralocus patterns of linkage disequilibrium is geneconversion. However, geneconversion was ruled out in this case as precise excision events were occurring in homozygotes. Thus, the observed phenomena can be explained by imperfect and repeatable geneconversion-like events, assigned to specific locations in chromosome 17. Both geneconversion and cross-over are often referred to as recombination and terminology is sometimes not clearly defined. An important contribution of geneconversion to meiotic recombination helps to explain our observation, but does not appear to be sufficient.
