Answer:
The phenotypic variation for the trait is continuous
Explanation:
Genetically speaking, quantitative traits are controlled by many genes, classes are not easily distinguishable and there is a continuous distribution of the phenotype. These characteristics refer to measurements of quantities (weights, volumes, measurements: kg, m, cm, g, m2, etc.).
In other words, quantitative characteristics are those that exhibit continuous variations and are partly of non-genetic origin; that is, they are greatly affected by the environment.
