Our DNA which is responsible for a particular trait is the set of genes in which is called genotype. The physical expression, or characteristics, of that trait is called phenotype. The two organisms, for example, that have even the minutest difference in their genes are said to have different genotypes. The information that is inside a gene, which is genotype, is what makes up the trait, or the specific organism genetic is what makes it up. The visible or observable expression combined with the environmental of the results of genes, and the influence on an organism’s appearance or behavior is what you see in phenotype.
