For the TX300, the proportion of unavailable data was higher (circa.17) for both participants; the mean duration of raw data fragments was 2,100 ms for participant 1 and 1,500 ms for participant 2. Within-fixation variance was below 0.1° for both participants.
For the Eyelink 1000, the proportion of unavailable data was less than.04 of the total viewing material presented for both participants, the mean duration of raw data fragments was 9,800 ms for participant 1 and 3,300 ms for participant 2, and average within-fixation variance was approximately 0.12° for both participants.
Whereas the mean of the POR during fixations does not vary systematically across tasks, the within-fixation variation ∑ does, even if not by very much (the explained variance equals.05 for the x-direction, and.08 for the y-direction, see Table 4).
Their presence or absence has substantial effects on key genetic features of populations like genetic variance, heritability, fixation rates of alleles, and long-term selection response.
Because Km and Kf weight male (Gm) and female (Gf) fitness gradients independently in the probability of fixation (Equation 1), reproductive variance may affect male and female evolution differently.
We characterized population structure within B. schlosseri for fester A-type, B1-type, and C-type alleles and all housekeeping genes using an analysis of molecular variance (AMOVA), fixation indices (Fct, Fsc and Fst), and pairwise Fst values between populations in Arlequin 3.5.1.2 [ 68].
The significance of the fixation indices and of the variance components was assessed using 10 000 permutations.
All variance components and fixation indices were large and significantly different from zero.
In our example, the variance around the fixation states is much more limited than at the interior states of the triangle (Additional file 4 ).
The analysis of non-synonymous substitution fixation rate revealed that the variance in dN was significantly larger in C. resedifolia than in C. impatiens (6.6 × 10-15 vs. 9.2 × 10-15; F test, P < 10-15, also when correcting for gene length).
Haplotype (h) and nucleotide (p) diversity were calculated in each site using Nei algorithms [ 41], while the fixation index (FST) and molecular variance (AMOVA) were established using DnaSP 4b10.9 [ 42] and Arlequin 3.5 [ 43].
