Here's a breakdown:

* Genotype: The complete set of genes or genetic material present in an organism. This includes the specific sequence of DNA that makes up each gene.

* Phenotype: The observable characteristics or traits of an organism. These are influenced by the genotype and environmental factors.

For example, a person might have the genotype for brown eyes (two brown eye alleles), but their phenotype might be blue eyes due to environmental factors or other genetic interactions.

Think of it like this: the genotype is the blueprint, and the phenotype is the finished building.
