Verified
The pattern of phenotypic expression of a single genotype across a range of environments is
A) phenotypic plasticity.
B) a reaction norm.
C) a quantitative trait locus.
D) polyphenism.
Phenotypic Plasticity
Phenotypic plasticity refers to changes in the phenotype produced by a single genotype in different environments.
Reaction Norm
Reaction norm refers to the pattern of phenotypic expression of a single genotype across a range of environments. In a sense, reaction norms depict how development maps the genotype into the phenotype as a function of the environment.
Genotype
Genotype describes the genetic makeup of an individual. Although a genotype includes all the alleles of all the genes in that individual, the term is often used to refer to the specific alleles carried by an individual for any particular gene.
- Assess the contributions of genotype-environment interactions to differences in phenotype.
- Differentiate between phenotypic plasticity and genetic evolution as mechanisms for responding to environmental changes.
