Although many studies report no sex difference in Carabelli trait expression, others have found that males are more likely to express the Carabelli cusp than females [20], [29].
Situation trait relevance, trait expression, and cross-situational consistency: testing a principle of trait activation.
Skinner, M. M. et al. Dental trait expression at the enamel-dentine junction of lower molars in extant and fossil hominoids.
These results reinforce the negative impact of emotional trauma and people's resilience to physical trauma, which may even translate into adaptive trait expression in males particularly.
Trait expression was measured in simple laboratory bioassays on small size groups of snails, and under more complex, indoor microcosm conditions, on larger groups of snails.
Biotech trait expression could also be limited to roots to minimise expression in harvested parts, and this could improve public acceptability.
The new research shows the Brewster's form of golden- and blue-winged warbler hybrids seems to be an expression of dominant traits for throat and body color, whereas the Lawrence's form of hybrid exhibits recessive trait expression for both.
There were significant levels of variation of more than 25% relative standard deviation (RSD) in antioxidant capacity among the 32 tested genotypes; and that genotype, environment, and genotype-by-environment (G × E) interaction all significantly (P < 0.05) affected trait expression.
A lack of genetic variance in male traits in the direction of sexual selection may represent a general feature of sexually selected systems, even in the presence of condition-dependent trait expression.
Indeed, trait expression has to be plastic to ensure balanced source-sink relationships under variable resources.
Analyses of variance were then used to examine the differences in trait expression assuming a randomised complete block structure.
