Detailed explanation-1: -Agenotypeis the genetic makeup of an individual organism. Biologists use the term genotype to distinguish from phenotype, which consists of the observable characteristics of an organism.
Detailed explanation-2: -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-3: -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).
Detailed explanation-4: -A person’s genetic makeup is called a genotype.
Detailed explanation-5: -Each pair of alleles represents the genotype of a specific gene. Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism.
