✦ Synopsis

Recombinational load
A decrease in mean fitness due to the break up of co-adapted (that is, epistatic) gene combinations by recombination.
Drift
A change in genotype frequencies due to chance variation. Also known as random or genetic drift.
Epistasis
Deviation from independent (that is, multiplicative) gene action on a polygenically encoded phenotype, or on fitness.
