Multiple Choice
The ability to change phenotype in response to local environmental conditions is called:
A
Phenotypic plasticity
B
Pleiotropy
C
Epistasis
D
Genetic drift
Verified step by step guidance
1
Understand the concept of phenotype: A phenotype refers to the observable traits or characteristics of an organism, which can be influenced by both genetic and environmental factors.
Define phenotypic plasticity: Phenotypic plasticity is the ability of an organism to change its phenotype in response to environmental conditions. This allows organisms to adapt to varying environments without altering their genetic code.
Clarify pleiotropy: Pleiotropy occurs when a single gene influences multiple traits. It is not related to the ability to change phenotype based on environmental conditions.
Explain epistasis: Epistasis refers to the interaction between genes, where the expression of one gene can affect or mask the expression of another gene. This is unrelated to environmental adaptation.
Describe genetic drift: Genetic drift is a mechanism of evolution that involves random changes in allele frequencies within a population over time. It does not involve changes in phenotype due to environmental conditions.
