Genotype (Short Note)

The sum total of all the hereditary units or genes which an organism contains are together known as genotypes. Briefly it means that phenotypes are not inherited, only the genes which control the development of phenotypes are indeed inherited. Whatever is the phenotype of an animal, it is not the result of genotype only but is accumulative result of the interaction of the genotype and environment. The organism having same genotype might produce different phenotypes in different types of environment. However the ability of an organism to produce a character is largely determined by its genotype, although the environment can modify the action of a gene. In brief neither the genes alone nor environment alone can produce a character. The development of phenotype actually depends upon the factors i.e. genes and surrounding environment.
