Key Stage 4
Meaning
A genotype is a set of genes responsible for a particular physical characteristic.
About Genotypes
- The genotype of two identical twins is the same.
- 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.
