In a revision of her 2012 PhD dissertation at the University of Copenhagen, Halvegaard explores two highly elaborate examples of audible revelations from the Nag Hammadi collection: the Thunder: Perfect Mind (NHC VI,2) and the Trimorphic Protennoia (NHC XIII,1), both of which describe goddesses descending in auditive terms as sound, voice, and word.
She had a long relationship with Fisher, who invited her to work with him on her problem of inheritance in trimorphic flowers.
Capitula isomorphic, dimorphic, or trimorphic. Style branches dorsally smooth or with papillae completely covering the branches or only the branch apex, very rarely extending below the branch bifurcation point Tribe Mutisieae 2b.
During the fall of 1988, 21-46 (mean = 38) seed families were randomly collected from each style morph in three trimorphic populations from the eastern Ontario study area (EO-T3, EO-T6, EO-T7).
Florets trimorphic; marginal florets female, without staminodes, corolla true ray to bilabiate with minute inner lips, outer lip expanded or not; intermediate florets female, staminodes absent, corolla filiform irregularly tubular, true ray to bilabiate, shorter than the style; central florets bisexual, corolla bilabiate to tubular-bilabiate; anther apical appendages acute, tails smooth to papillose; style bifid, branches dorsally papillose.
Hence, O ranges from zero for monomorphic populations to unity in trimorphic populations with even morph frequencies.
The home contained a large garden that enabled Nora to continue some of her genetics research on trimorphic flowers.
For example, species may show dimorphic or trimorphic wood-producing fibers in the juvenile stem, and only vessels and parenchyma develop as vascular cambium matures in older plants, such as Epiphyllum, Hylocereus.
They further predict that morph frequencies in trimorphic populations should not be consistently biased towards any particular morph (but see Heuch 1980; Morgan and Barrett 1988).
Figure 1c, on the other hand, demonstrates a numerical example of a trimorphic ESS for a truncated bi-exponential distribution of [Theta] with Q [greater than] 1.
paniculata may represent a weak heteromorphic incompatibility system because the observed patterns of pollen-tube growth parallel pollen-tube growth and seed-set patterns that occur in related species with strong trimorphic incompatibility.
