Which Description Applies to Typical Quantitative Traits

Question

Which description applies to typical quantitative traits?
A) Such traits are easy to follow using Punnett squares.
B) Such traits are not affected by the environment.
C) Such traits are usually influenced by only one gene.
D) Such traits show continuous variation.

Accepted Answer

Quantitative traits show continuous variation, meaning that there is a range of phenotypic expression rather than distinct categories. They are often influenced by multiple genes and the environment, which makes them difficult to predict using Punnett squares.
