Understand the term 'genotype': In biology, the genotype refers to the genetic makeup of an organism. It includes all the genes that an organism carries, which are inherited from its parents.
Differentiate between genotype and phenotype: While genotype is the genetic constitution, phenotype refers to the observable physical traits and characteristics of an organism, which result from the interaction of the genotype with the environment.
Consider the options provided: The correct answer should relate to the genetic makeup, not the physical traits, environment, or behavior patterns.
Identify the correct option: The option that describes the genetic makeup of an organism, including all of its genes, is the correct definition of genotype.
Reflect on the importance of genotype: Genotype plays a crucial role in determining the potential traits and characteristics an organism can exhibit, although the environment can influence the expression of these traits.
