What is a phenotype and how does it differ from a genotype?

From these two concepts, the genotype emerged earlier. It was he who, when interacting with the outside world, gave rise to the phenotype. A genotype is a set of genes that are transmitted from generation to generation. And the phenotype is the external and internal characteristics, properties or traits of a particular organism. These include:
– external (pigmentation, hair structure, color and shape of the eyes, shape of the ears and nose);
– anatomical (location and structure of organs);
– physiological (cell structure);
– biochemical (hormone composition, protein structure).
A distinctive feature of the genotype about the phenotype is expressed in the primary source of data (the genotype is recognized from DNA, the phenotype is recorded on the basis of external data) and in the type of education (the phenotype is influenced by external factors and mutations, and the genotype is unchanged).
