NEET BIOLOGY

Detailed explanation-1: -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-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. While an organism’s genotype is directly inherited from its parents, phenotype is merely influenced by genotype.

Detailed explanation-3: -There are about 20, 000 genes in each cell of the human body. Together, they make up the blueprint for the human body and how it works. A person’s genetic makeup is called a genotype.

Detailed explanation-4: -Genotype. A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. The genotype is expressed when the information encoded in the genes’ DNA is used to make protein and RNA molecules.

Detailed explanation-5: -Specifically, to detect the underlying genotype of an organism with a dominant phenotype, one must do a type of breeding analysis called a test cross. The test cross is another fundamental tool devised by Gregor Mendel.
