Explain what is meant by the term phenotype.

The phenotype is the observable physical and biochemical characteristics of an organism, resulting from the interaction between its genotype and environmental factors.

Step-by-Step Solution:
Phenotype = Observable traits (e.g., height, eye color, enzyme activity)
Determined by: Genotype (genetic makeup) + Environmental factors
Can change over time even if genotype remains constant
Example: Plant height (phenotype) depends on genes AND growing conditions

Key Mistake to Avoid:
Students often focus only on physical appearance and forget to include biochemical characteristics or environmental influences in their definition.

Quick Tip:
Remember the equation: Phenotype = Genotype + Environment. Use real-world examples like identical twins in different environments to reinforce your understanding.
