The genetic makeup of an organism is called its genotype while the physical traits of an organism are called its phenotype.
To elaborate, the genotype refers to the specific alleles and genes an organism carries, which can influence various traits, while the phenotype encompasses how those genetic traits are expressed in the organism’s physical characteristics and behaviors. For example, two plants may share the same genotype for flower color, but environmental factors can affect how this trait is expressed, resulting in different phenotypes.
