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: -A person’s genetic makeup is called a genotype.
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. While an organism’s genotype is directly inherited from its parents, phenotype is merely influenced by genotype.
Detailed explanation-4: -A person’s genotype is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. Phenotype is the detectable expression of this genotype – a patient’s clinical presentation.
Detailed explanation-5: -A genotype is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.
