Inheritance of quantitative traits is characterized by

Large and non-additive gene effects Large and additive gene effects Discontinuous variation Environmental conditions Correct

Genetics of Quantitative Traits:
Quantitative traits (e.g., egg production, body weight, growth rate) are controlled by numerous polygenes having small, cumulative additive effects.
They exhibit continuous variation and are highly susceptible to modification by environmental conditions (feed quality, ambient temperature, housing, disease challenge).

Correct option: (4) Environmental conditions
