Questions: 15 | Attempts: 20 | Last updated: Mar 19, 2026

Sample Question 1
What is phenotypic plasticity?

The ability of a genotype to remain unchanged regardless of the environment

The ability of a single genotype to produce different phenotypes in response to different environmental conditions

A permanent genetic mutation caused by environmental stress

The process by which organisms evolve new genes in response to the environment

Sample Question 2
Phenotypic plasticity involves a permanent change to an organism's DNA sequence in response to the environment.

True

False

Sample Question 3
A plant grown in low light conditions develops larger, thinner leaves than the same species grown in bright sunlight. This is an example of what?

A genetic mutation caused by shade

Phenotypic plasticity in response to light availability

Discontinuous variation between two different species

Natural selection acting on leaf shape genes
