Title: meiotic drive Long Title: IUPAC Gold Book - meiotic drive DOI: 10.1351/goldbook.14842 Status: current Definition Any process that causes some alleles to be over-represented in the gametes which are formed during meiosis. Note With normal Mendelian segregation at a genetic locus, on average half of an organism’s offspring inherit one of the alleles and the other half the other allele. This term refers to rare cases in which Mendel’s laws are broken, and one of the alleles is consistently found in more than half the offspring. Source - PAC, 2009, 81, 829.
