Generally decreased by inbreeding and increased by adaptability, identify this evolutionary measure of reproductive success, the contribution of an indi- vidual to the gene pool of the next generation, which usually goes up the longer an individual survives.
The probability distribution of phenotypes is part of Hartl's definition of this concept, and an altruistic act must increase this quantity to pass Hamilton's rule. The inclusive variety of this explains why worker bees care for their sis- ters, and when most alleles are neutral for this quantity, genetic drift overtakes natural selection. Most courtship be- havior is driven by the relative type of this quantity, for which mules rate a zero.
