Medical Definition of Gene conversion
1.
A phenomenon in which alleles are segregated in a 3:1 not 2:2 ratio in meiosis. May be a result of DNA polymerase switching templates and copying from the other homologous sequence or a result of mismatch repair (nucleotides being removed from one strand and replaced by repair synthesis using the other strand as template).
