Furthermore, several researchers have argued that reduced fertility in schizophrenics' relatives supports a strict mutation-selection model in which schizotypy-increasing alleles are not maintained nor favored by selection [9], [10], [12].
The GSM parameter is randomly drawn in the uniform distribution 0.0 (strict stepwise mutation model) to 0.1.
We found that the requirement for Phe at this position is strict, as mutation of this residue to alanine or tyrosine or tryptophan results in significantly decreased binding affinity for uridine while not affecting the stability significantly.
Estimates of H eq under MDE were obtained assuming a strict stepwise mutation model (SMM) and two-phase models (TPM) with proportions of indels larger than one repeat of 10%, 20%and30%0%and30%
This software computes the average heterozygosity, which is compared to the observed heterozygosity to determine if a locus expresses a heterozygosity excess/deficit, according to the strict Stepwise Mutation Model (SMM [ 59]).
In this analysis, Φst (for mtDNA), FST, and RST (both for microsatellite data, the latter assuming a strict stepwise mutation; Slatkin 1995) were calculated to determine the overall and pairwise levels of differentiation among different subspecies.
As the fitness of the wild type is a specific value of the continuous random variable, the probability of having a strict neutral mutation, the fitness of which is equal to the fitness of the wild type, is 0. Thus, the average fitness is only maintained when the mutant goes extinct, which occurs with probability (14) p (W ¯ (0 ) = d ) = p (b < d ) = 1 − θ.
Five microsatellite loci used in the population genetic analyses have complex repeat motifs and therefore may not follow a strict step-wise mutation model.
In a subject carrying an LHON mutation, the strict temporal sequence of prolonged appreciable occupational exposure followed by sudden onset of visual loss must raise a suspicion of causality (with a possible further interaction with tobacco smoke).
Nevertheless, in a subject carrying an LHON mutation, the strict temporal sequence of a prolonged appreciable occupational exposure followed by sudden onset of visual loss must raise a suspicion of causality.
