The two terms are often used at the same time to describe the same organism, but there is a difference between genotype and phenotype: An organism's genotype is the set of genes in its DNA responsible for a particular trait. An organism's phenotype is the physical expression of those genes.
|The hereditary information of the organism in the form of the gene in the DNA and remains the same throughout the life.||The characters of an organism that are visible are known as phenotypes.|
|Present inside the body as genetic material.||Expression of genes as the external appearance.|
|It can be determined by scientific methods such as the polymerase chain reaction.||It can be determined by observing the organism.|
|It is affected by genes.||It is affected by genotype and environmental conditions.|
|For eg., Blood group, eye color, height, genetic diseases.||For eg., Weight, physique, beak of birds.|
