The genetic make-up of an organism is described as its genotype. This refers to the complete set of genes and genetic material present in an organism, including both the dominant and recessive alleles for each trait. Genotype plays a critical role in determining an organism's physical characteristics, known as its phenotype. While the genotype represents the genetic potential of an organism, the phenotype reflects how that potential is expressed in the organism's physical traits. Therefore, by studying an organism's genotype, scientists can make predictions about the traits that the organism will display in its phenotype.
