These models were chosen to represent the variation found in SSI systems: codominance
in both pollen and style is reported in Caryophyllaceae (Lundquist 1994), codominance
in the style and dominance hierarchy in the pollen is described in Brassicaceae (Ockendon 1974; Stevens and Kay 1989), and dominance hierarchy in pollen and style is found in Asteraceae (Samaha and Boyle 1989) and Convolvulaceae (Kowyama et al.
The local codominance
of such a guild of legumes on this edaphically extreme site suggests that there is a selective advantage in the trees being ectomycorrhizal as opposed to being arbuscular (or non-) mycorrhizal.
This pattern of codominance
may reflect different advantages of each species under different environmental conditions.
The availability and abundance of SSR markers throughout the cotton genome, their polymorphic nature, codominance
, and polymerase chain reaction (PCR)-based assay make SSRs useful in detecting genetic diversity (Reddy et al.
Because the initial experiment was designed for the analysis of a fertilizer treatment response, trees were selected for codominance
in the canopy and understory trees were avoided.
They also exhibit other desired qualities, that is, neutrality, Mendelian inheritance, and codominance
The mean basal areas for each species from the baseline runs [ILLUSTRATION FOR FIGURE 7A OMITTED] show a familiar successional pattern, with shade intolerant species initially dominant, but declining after reaching peak abundances between years 100 (WA) and 400 (YB), and subsequent late successional codominance
by Be and Hm.
For example, Themeda triandra, a highly palatable East African savanna grass, suffers [approximately equal to]80% mortality from ungulate grazers when not associated with other, less palatable grass species; however, as codominance
with unpalatable species increases, mortality of Themeda rapidly decreases (McNaughton, 1978).
1996), which benefit from their high polymorphism, heterozygosity, codominance
, and wide transportability across different mapping populations.
The genotype assignment test makes full use of the data, including codominance
of SSR markers.
is possible, as the average fixation time with codominance
is on the order of 135 [+ or -] 50 generations.
Canonical discriminant analysis of southwestern riparian community types indicated a trend toward Salix dominance on low-elevation sites, and codominance
of this species with Populus at middle elevations (Szaro 1989).
