Question

How are genotypes and phenotypes related?

Answer 1

Phenotypes are genotypes that have interacted with the environment.

Explanation:

The genotype is an individual's collection of genes.
The phenotype is the expression of the genotype in a certain environment.
It means that two clones, with exactly the same genotype, will not look the same (will have different phenotypes) if they are raised in different environments.

Here, the red line symbolize all the phenotypes (P) that can be expressed by one individual's genotype (G).
Depending on which environment (E) the individual is living, the phenotype will change but the genotype will be the same.
