quantitative character
A heritable feature in a population that varies continuously as a result of environmental influences and the additive effect of two or more genes (polygenic inheritance).

(c) Typically s can vary over a significant range controlled by their underlying genetics
(d) For example, height and skin color (in humans) are s ...

Quantitative characters are those that vary along a continuum within a population.
For example, plant height in a wildflower population ranges from short to tall.

While Darwin was wrestling with pangenesis Galton was pioneering the analysis of the inheritance of s and he documented with extraordinary insight the properties of such inheritance.

[1] Completely homozygous genotypes are precisely repeatable and hence heritability of quantitative characters is increased leading to improved selection efficiency.
