Key Stage 4

Meaning

The phenotype is the physical expression of the genotype.

About the Phenotype

A different genotype in two organisms can result in the same phenotype. For example two people may both have a phenotype of brown eyes but one has a genotype containing two copies of the allele for brown eyes while the other may have one copy of the allele for blue eyes.
The phenotype is determined by the dominant alleles in the genotype.
