Conflict among genetic elements whose transmission or expression favours different outcomes despite residence in one organism. Organismal performance alone is not the relevant fitness currency for every element.
Transmission distortion favouring an element over the Mendelian expectation. In a strict usage this acts during meiosis; broader usage also includes biased survival of gametes.
Biased transmission associated with centromere differences during asymmetric meiosis, where only some meiotic products contribute to the next generation.
A modifier reducing a driver’s transmission advantage or harmful consequences. Selection depends on linkage, background and the costs of suppression.
Deviation in inherited allele proportions from the Mendelian expectation. Embryonic viability selection can also distort offspring counts and must be separated from gametic transmission bias.
