Group of answer choices

Two genetically identical plants are grown in different environments. Differences in gene expression result in different phenotypes.

 

100 seeds randomly chosen from a population are placed in each of two environments. Those that germinate have different phenotypes.

 

After a geographic barrier separates two populations of plants, the plants on one side of the barrier are taller on average.

 

Higher mutation rates are observed in one environment than another.
