By increasing homozygosity of deleterious recessive alleles, inbreeding depression often reduces this quantity.
The transmission term in the Price equation takes the expected value of this quantity times the character change. Fisher's fundamental theorem predicts that the rate of increase in this quantity is proportional to its additive genetic variance. Sewall Wright visualized changes in this quantity as moving along a high-dimensional (*) landscape. The "absolute" variety of this quantity is the ratio of individuals with a certain genotype after and before selection. Kin selection promotes altruism by increasing the "inclusive" variety of this quantity. Neutral mutations have no effect on it. By increasing homozygosity of deleterious recessive alleles, inbreeding depression often reduces this quantity. For 10 points, name this term denoting an organism's ability to survive and reproduce in a given environment.
The transmission term in the Price equation takes the expected value of this quantity times the character change.
