The Meiotic Drive: Intragenomic Competition and Selection

Abstract The article considers the distribution and mechanisms of the meiotic drive as a phenomenon manifested in unequal transmission of gene alleles and/or homologous chromosomes into gametes during meiosis. The meiotic drive has been studied in the most detail in Drosophila , mice, corn, and ascomycete fungi of the genera Neurospora and Podospora . The consequence of the meiotic drive is a shift in the frequencies of alleles in the gene pool and the maintenance of nonadaptive traits in the population.
