definition of genotype

At the behest of the biology, the genotype turns out to be the set of characteristic genes of each species, plant or animal, that is to say, the genotype are the genes in DNA format that an animal, a plant or a human being inherits from its two parents, mother and father, and that therefore it is made up of the two chromosome endowments that contain the genetic information of the being in question.

The genes responsible for the transmission of inheritance characters always remain in the nucleus of the cell and it will be from there that they control the synthesis of proteins that occurs in the protoplasm.

While, the genotype is outwardly manifested as a phenotype, which is nothing other than the Differential physical traits of individuals, such as the color of hair, eyes, skin, among others and that is also intimately influenced by the environment in which the individual in question lives and develops, then, the genotype is the genes of an individual and the phenotype the traits. The genotype can be distinguished by observing the DNA, while the type of phenotype can be known through the observation of the external appearance of an organism.

The phenotype will also manifest itself in hereditary diseases; what the doctor will warn about a disease is the phenotype and from the extreme observations that he makes, he will be able to make assumptions about the genotype.

Not always the relationship between genotype and phenotype turns out to be so direct, since a phenotype can result from several genotypes and many of these are plausible to receive a lot of influence from the environment.

Genetics is the biological discipline that deals with the study of genotypes and their external manifestations, phenotypes.
