Genotype, the genetic constitution of an organism. The genotype determines the hereditary potentials and limitations of an individual from embryonic formation through adulthood. Among organisms that reproduce sexually, an individualâs genotype comprises the entire complex of genes inherited from both parents.
Genotype -- the sum total of all the alleles at all the loci in a organism. While precise and concise, this definition is not very useful. The genotype may also apply to genetic material at a single genetic locus and describe the alleles that an individual possesses at a particular locus.
