PATHOLOGY

Detailed explanation-1: -Genotype is the genetic makeup of an individual cell or organism that determines or contributes to its phenotype. The contrasting terms genotype and phenotype are used to define the characteristics or traits of an organism.

Detailed explanation-2: -An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele.

Detailed explanation-3: -Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
