Verified step by step guidance

Understand the definitions: Genotype refers to the genetic makeup of an organism, which includes all the genes inherited from the parents. Phenotype refers to the observable characteristics or traits of an organism, such as its morphology, development, biochemical properties, and behavior.
Recognize the relationship between genotype and phenotype: The genotype provides the blueprint for the phenotype, meaning that the genetic information can influence the traits that are expressed.
Consider the role of the environment: While the genotype sets the potential for certain traits, the environment can significantly influence the expression of these traits. For example, identical twins with the same genotype can have different phenotypes if they are exposed to different environmental conditions.
Identify the false statement: The statement 'Phenotype is solely determined by genotype without any influence from the environment' is false because it ignores the impact of environmental factors on the expression of traits.
Summarize the correct understanding: Both genotype and environmental factors contribute to the phenotype of an organism. The interaction between genes and the environment is complex and can result in a wide range of phenotypic outcomes.
