How is it possible for a single genotype to generate a broad range of phenotypes?
What will be an ideal response?
Answer:
Organisms may have identical genotypes, but depending on their environment, expression of some genes may be more beneficial than others. Thus, environmental factors can regulate which genes are expressed at any one point in time, allowing for different phenotypes (physical expression), from a single set of genes.
