Aita et al. proposed a "rough Mt. Fuji" model to describe these constructs. The first and second derivatives of these constructs can be used to calculate the changes in a variance- covariance "inheritance matrix" denoted by the letter G. A "tunably rugged" example of these constructs is described by Kaufmann's NK model. The mechanism by which points on these constructs move toward a global maximum without getting "stuck" at a local maximum can be described by the "shifting balance" theory proposed by Sewall Wright. Allele frequencies are often used as the dependent variables on these graphs, whose "valleys" can be crossed by genetic drift and whose "peaks" tend to be reached when selection is strong. For 10 points, name these graphs which depict how the fitness of an organism changes due to changes in genotype.
