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.
