Here's the breakdown:
* Genotype: This refers to the genetic makeup of an organism. It's the specific combination of alleles (versions of a gene) an individual possesses. For example, someone might have the genotype "BB" for eye color, meaning they have two copies of the "B" allele.
* Phenotype: This refers to the observable characteristics of an organism, which are the result of the genotype. This includes physical traits like eye color, height, or hair color, as well as less visible traits like susceptibility to certain diseases.
Think of it like this:
* Genotype: The recipe for a cake.
* Phenotype: The actual cake that's baked.
The genotype provides the instructions, while the phenotype is the actual outcome.
In summary:
* Genotype: The genetic code, the blueprint.
* Phenotype: The physical manifestation of the genotype, the actual expression.
