Final answer:
The environment can affect an organism's phenotype through factors like sunlight and temperature. For example, sun exposure can lead to darker skin color, and temperature can determine the sex of some reptiles.
Step-by-step explanation:
The environment can affect an organism's phenotype in various ways. One example is the effect of sunlight on skin color. People who spend more time in the sun tend to have darker skin compared to those who spend most of their time indoors. Another example is temperature-dependent sex determination in some reptiles, where the temperature at which the eggs are incubated determines the sex of the offspring.
