Environmental factors that can affect gene expression can include:
1. **Temperature**: Changes in temperature can influence how genes are expressed, as certain proteins may become activated or inactivated under different thermal conditions.
2. **Nutrient Availability**: The availability of nutrients can determine the metabolic pathways that are activated and thus affect which genes are expressed.
3. **Chemical Exposure**: Exposure to certain chemicals, including pollutants and toxins, can lead to changes in gene expression, often through mechanisms such as methylation or histone modification.
4. **Light**: For many organisms, particularly plants, light can trigger responses that lead to changes in gene expression, such as flowering.
5. **Stress Factors**: Physical stressors (like UV radiation) or biological stressors (such as infections) can lead to altered gene expression patterns as the organism responds to these challenges.
6. **Social Interaction**: In many social animals, the presence or absence of certain social cues can alter hormonal levels and subsequently influence gene expression.
