🧬Genotype
- ✓The full set of genes an organism carries
- ✓The inherited genetic code itself
- ✓Cannot be seen directly without genetic testing
- ✓Stays the same throughout an organism's life
- ✓Determines the potential range of traits
👁️Phenotype
- ✓The observable physical and behavioral traits
- ✓The visible expression of the genotype
- ✓Can be seen and measured directly
- ✓Can change with environment, age and lifestyle
- ✓Results from genotype interacting with surroundings
Verdict
Genotype is the genetic blueprint; phenotype is the finished result you can observe. The same genotype can yield different phenotypes depending on environment, so genes set potential, not destiny.
Frequently asked
Can two organisms share a genotype but differ in phenotype?+
Yes. Identical twins share a genotype yet can develop differences from environment and lifestyle.
Does the environment affect genotype?+
Not the inherited code itself, but the environment strongly influences which traits appear in the phenotype.
Which can you observe directly?+
The phenotype. Genotype generally requires genetic testing to determine.
