Question

What about the Nemoria larval phenotype tells us it is a discrete facultative trait?

A) The phenotype is continuously variable.
B) The phenotype is not influenced by environmental conditions.
C) The phenotype is expressed only under certain environmental conditions.
D) The phenotype is not genetically determined.

Answer 1

The Nemoria larval phenotype is a discrete facultative trait because it is expressed only under certain environmental conditions.

Step-by-step explanation:

The Nemoria larval phenotype is considered a discrete facultative trait because it is expressed only under certain environmental conditions (option C). This means that the phenotype is not continuously variable (option A) and is dependent on the presence or absence of specific environmental cues. Additionally, the phenotype is not genetically determined (option D) as it is influenced by environmental factors.
