Differences between genotype and phenotype
February 19, 2019
S.N | Genotype | Phenotype |
1. | It is the genetic make-up of an organism. | It is the morphological appearance of an organism. |
2. | By knowing the genotype, phenotype of individual can be assessed. | By knowing the phenotype, genotype may or may not be assessed.
|
3. | It remains the same throughout the life of an individual. | It may change with time and environment. E.g. infant, young and old. |
4. | It is not influenced by phenotype. | It establishes the boundaries within which a phenotype can be expressed. |
5. | It cannot be studied directly. | It can be known through direct observation. |
6. | Individuals with different genotypes may have similar phenotype. | Individual with different phenotype usually have different genotypes. |
7. | Examples- The gene responsible for the eye color.
The gene responsible for the hair color. |
Examples-phenotype is the physical appearance of that like hair color, eye color, weight, the ability to roll one’s tongue. |
8. | Partly inherited by offspring, as one of the two alleles is passed on during reproduction. | Cannot be inherited. |
