Individual traits with their symbols and permissible values.

Values are listed as an interval [a, b], a set of discrete values (a, b), a range of integer values a–b, or “any” to indicate that all real values are allowed. Traits above the separating line (x, y, z, S) are genetic (heritable, and immutable for any given individual); traits below the line (o, p, s) are non-genetic (not heritable, and subject to change for each individual over time).Individual traits with their symbols and permissible values.
