Which of the following are true about phenotypic plasticity? answer choices A-A change in the phenotype through phenotypic plasticity allows organisms to adapt to their current environment (for example, from not being cold-resistant to being cold-resistant) B-The difference between the two phenotypes in question is based on an allelic difference between the two (for example, cold-resistant and not cold-resistant are based on two different alleles of the same gene) C- Both D-Neither
Imagine that you travel around the world and find two populations of fish that look very similar, but one one population lives in a cold climate and is very cold-resistant (produces an antifreeze protein), while the other population lives in warm climate and is not cold-resistant (and does not produce the antifreeze protein). This is the kind of example that biologists try to explain, and think about whether it is due to phenotypic plasticity or selection. Let's think through this with a series of questions.
