A meiotic process of directed
change in which one allele directs the conversion of a partner allele
to its own form. In asci of Ascomycete fungi a 4:4 ratio of alleles
is expected after meiosis, yet 6:2 and 5:3 ratios are sometimes observed.
A model of recombination, produced by Holliday, suggests that gene
conversion may be explained by repair of heteroduplex DNA. |
