Flavour is a complex trait under large environmental and seasonal effects which already poses a challenge to breeders and will be more problematic with extreme weather events and climate changes.
Another possible reason is that IMF content is complex trait, for which gene-gene and gene-environment interactions possibly have different genetic effects across population.
In soybean, grain yield, as in other crops, is a complex trait because it results from the expression and association of different components (El-Mohsen et al., 2013).
Height is a complex trait that may serve as an effective phenotype model for other complex traits and diseases because it is a noninvasive and easily-measured phenotype to study.
"An important finding of this work is that the resistance trait is a complex trait controlled by many genes, which makes it a bit harder to work with.

In general, cross-pollinating species exhibit lower levels of LD or higher levels of LD decay than the self-pollinating species [54]; therefore, comparatively higher number of DNA markers would be required in case of cross-pollinating species to unravel the molecular mechanism of any complex trait. However, variations in the levels of LD decay have also been reported within species and from locus to locus within a particular genome [67].
Because the reward pathway we previously discussed (Cunningham et al., 2012) is involved in addiction to many drugs, the dopamine-receptor encoding gene, D2DR, has been strongly implicated in a complex trait referred to as "reward deficiency syndrome" (Blum et al., 1996).
The identification of trans eQTL clusters can be a powerful approach for identifying key regulators underlying a complex trait of interest.
For a proper estimation of honey quantity, which is a complex trait, there were taken in consideration, besides productivity parameter and reproduction index (queens prolificness, developing of nest brood), the precocity of developing the bee colony at the beginning of the keeping season, family resistance to the winter season, diseases resistance, and behaviour index (aggressiveness/ gentleness, tendency of swarming, running on the honeycomb, etc.).
