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. (15[1])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,” (15[1])Tomoko Ohta developed (15[1])a (*) “nearly” (10[1])modification of this theory. (10[1])In this theory, the genetic fixation probability (10[1])equals 1 over 2 times the population size, and the mutant substitution (-5[1])rate equals the gamete mutation rate, (10[1])thus explaining the constancy of the “molecular clock.” For 10 (10[1])points, name this theory (10[2])formulated by Motoo (10[1])Kimura, (10[2])which posits that most allele changes occur (10[1])due to genetic drift and that most molecular evolution causes no change to fitness. ■END■ (0[7])
