| Definition | A genetic event that can occur in the dividing cells of a diploid organism heterozygous for one or more markers, in which a daughter cell becomes homozygous or hemizygous for one or more alleles through mitotic recombination, deletion, or gene conversion. "Loss of heterozygosity (LOH)" events are often important steps in tumor progression. |
