Detailed explanation-1: -(JEE-noh-tipe) At its broadest level, genotype includes the entire genetic constitution of an individual. It is often applied more narrowly to the set of alleles present at one or more specific loci.
Detailed explanation-2: -Encyclopedic Entry Vocabulary. In one sense, the term “genotype”-like the term “genome”-refers to the entire set of genes in the cells of an organism. In a narrower sense, however, it can refer to different alleles, or variant forms of a gene, for particular traits, or characteristics.
Detailed explanation-3: -An individual’s genotype is the combination of alleles that they possess for a specific gene. An individual’s phenotype is the combination of their observable characteristics or traits.
Detailed explanation-4: -An organism’s genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).
