The formulator of this theory created namesake “two-parameter” and “three-parameter” distances compatible with it. So long as “the absolute value of 2 N sub E times s” is less than 1, this theory holds for things that don’t “strictly” have its namesake property. This theory replaced a “balance hypothesis” based on overdominance in order to explain a dilemma that intensity is only 1 per 300 generations. Using a “fixed model,” Tomoko Ohta developed a (*) “nearly” modification of this theory. (10[1])In this theory, the genetic fixation probability equals 1 over 2 times the population size, and the mutant substitution rate equals the gamete mutation rate, thus explaining the constancy of the “molecular clock.” For 10 points, name this theory formulated by Motoo Kimura, (10[1])which posits that most allele changes occur due to genetic drift and that most molecular evolution causes no change to fitness. ■END■ (0[2])
