Primroses have white flowers when grown above 32°c but red flowers when grown at 24°c. this interaction between phenotypic expression and environment is an example of

The interaction between phenotype expression and the environment is an example of enviromental influences

Anything which depends on phenotype is genotype which includes genetic material codes molecules and structures which are not visible.
