Within an organism, phenotypes may change while genotypes remain constant.

The environment is responsible for generating different phenotype from same  genotype.

Explanation:

The genotype is set of genes. The genes are present on DNA and are responsible for particular character. The phenotype is observable  character produced from genotype. The mutation allows the changes in the genotype.

The same genotype shows various phenotype when it is exposed to different environment.
