The goal is to compare tests based solely on population genetic data with tests using comparative data or a combination of comparative and population genetic data.

WebMar 1, 1993 · Under the assumption of selective neutrality, the expected number of external mutations is equal to theta = 4Ne mu, where Ne is the effective population size and mu is the rate of mutation per gene per generation. Interestingly, this expectation is independent of the sample size. The number of external mutations is likely to deviate from its ...

WebFeb 17, 2024 · The first, selective neutrality, suggests that variations within personality traits are genetic noise because they make no difference to evolutionary fitness. However this seems very unlikely, since the major personality traits correlate with behaviours directly relevant to survival, such as mating, socializing and aggression. WebSelective Neutrality The neutral theory was first put forward by M. Kimura, and later by J. L. King and T. H. Jukes. Under selective neutrality in the strict sense, which was mainly developed by Kimura and his associates, the behavior of mutant alleles in the population is solely controlled by random genetic drift, and the theory becomes simple. geoff andre feyaertsWebAbstract.
