Definition of Genotype



The genotype is the set of genes present in an organism that can be transferred from the parental generation to the offspring. It can also be stated as the total genetic composition of an organism. The genes serve the purpose of imparting the characteristics of an organism that can be observed.

 


This expression of the genes is termed as phenotype and includes the eye color, hair color, height etc. the phenotype is generally determined by three factors i.e. genotype, environmental factors and epigenetic factors. The genotypes are commonly represented with alphabets such as BB, Bb and bb, where B is the dominant allele and b is the recessive one.
