All models considered at least two values for dominance: completely recessive (h = 0) and partially dominant (h = 0.1).
Note however, that our experiment lacks the resolution to exclude the possibility of pseudo-overdominance, which occurs when two partially dominant loci are linked in repulsion phase, inflating estimates of dominance effects.
However, it is straightforward to derive similar equations for the cases where the A2 allele is dominant, or partially dominant.
Cap color is controlled by one major locus on chromosome 8 and brown is partially dominant over white (Foulongne-Oriol et al. 2012a; Gao et al. 2015).
If A2 is dominant, or partially dominant, its equilibrium frequency will be lower than if it is completely recessive; for selection is more efficient at removing it from the population.
Female (F) is a partially dominant gene that controls femaleness.
If the allelic effect is only partially dominant, the fraction of NC1 alleles will increase accordingly.
This is confirmed by the detection of a biomass QTL with a partially dominant effect in this region (cf. Meyer et al. 2008 submitted).
Between 18 and 25 progeny of a cross between each sensitive line and a standard laboratory strain, yw, were scored, and six lines with aberrant heart beats were also aberrant when outcrossed, suggesting a partially dominant mode of transmission.
Finally, our model predicts that heterosis for most complex traits would arise primarily from complementarity between dominant or partially dominant regulatory genes and additive downstream ones, and inbreeding depression is due primarily to the breakdown of functioning FGUs by recombination.
In a simple mutation-selection balance model for partially dominant alleles (in a closed, panmictic, stationary population with an even sex-ratio), the estimated frequency of susceptible alleles q is q = μ/shetero, where μ is the rate at which susceptibility alleles arise in a new individual.
