The phrase "trivial traits" is correct and usable in written English.
It can be used to describe characteristics or qualities that are unimportant or insignificant. Here is an example sentence: "The book focused on the character's trivial traits, such as their favorite color and preferred brand of coffee, rather than their deeper motivations and flaws."
Amid all the debates around immigration, inclusion, English-speaking, heritage, Englishness v Britishness and identity: the seemingly trivial trait of cynicism seems to get lost, but might matter more than it seems.
The estimation of ancestral gene expression levels is not trivial, especially for traits that are heavily affected by negative selection and for which the ancestral values might therefore frequently fall outside the range observed in extant species.
Based on previous experiments, row column variation for SAM architecture traits is trivial when compared with plant-to-plant and chamber-to-chamber variation, hence the decision to use five full replications of each genotype with adequate checks.
Such increased performance under stressful temperatures may on the other hand induce non-trivial costs in other traits [4], [30], [57].
However, investment of limiting resources into expensive pollen or ejaculates [ 16] that maintain sperm competitiveness has also been demonstrated to come at non-trivial costs to other life-history traits in males [ 17- 19].
The evolutionary transition from phagotrophy to phototrophy is therefore non-trivial, and the intermediate stages that bridge the morphological traits associated with these two lifestyles are important to understand.
Given the many examples cited in this review, it is almost trivial to find genetic differentiation between populations living in contrasting habitats for traits important under global change.
(It is estimated that any specific gene effect accounts for less than 1% of the variance of complex traits [ 81].) The power limitations of relatively small twin studies are not trivial.
Understanding the complexity of these traits and accounting for the effects that are contributed by these genes and their interactions is not trivial.
