| Phenotype refers to the sum of a living organism’s observable characteristics |
In biology, a phenotype is defined as the observable traits or characteristics of an organism which is the result of the interaction of genes and environmental factors. These traits include physical appearances and any other traits that we can observe.
The phenotype of an organism includes its physiological, biochemical, and behavioural properties. Unlike genotype, which is inherited from the parents, the phenotype is affected by lifestyle and environmental factors. Environmental factors include temperature, nutrition, humidity and mental health of the organism.
For example, flamingoes are originally white in colour but turn pink due to pigments they acquire from their diet. Thus, flamingoes portray how they are influenced by environmental factors. It also suggests that the phenotype of an organism constantly changes, depending on the environmental factors.
