There is variation in traits.
The maintenance of genetic variation in traits under natural selection is a long-standing paradox in evolutionary biology1,2,3.
The same reasoning can be applied to quantitative traits, provided that genetic variation in traits is explicitly measured.
Local adaptation to contamination requires directional selection, genetic variation in traits relating to tolerance, spatial variability in exposure to the contaminant and limited gene flow between populations.
His research includes investigating genetic variation in traits related to mate choice such as pathogen disgust and avoidance, mate preferences, and the mental and behavioural aspects of masculinity and femininity.
Quantitative genetic analyses of dental variation on the pedigreed breeding colony of baboons housed at the Southwest Foundation for Biomedical Research in Texas enable us to model statistically how genetic, non-genetic, and covariate effects contribute to the overall population variation in traits such as tooth size, enamel thickness, and extra cusps on teeth.
Accordingly, highly variation in traits found in B. pilosa var.
Origin of variation: Some of the variation in traits among individuals has a genetic basis.
Using pictures of some of these wild relatives and scenarios that involve looking at the variation in traits (fruit size, flavor, etc).
We also found evidence that variation in traits can improve trait environment matching, a relationship which may facilitate our understanding ecological breadth along prevailing gradients, and community assembly on the basis of traits.
Analyzing the effect of species richness on stand productivity, as done in this study, could then potentially yield much clearer results, as the effects may not be hidden by intra-specific variation in traits.
