Background: Phenotype is how a genetic trait physically looks, while genotype is the trait expressed as two letters.
Example:
-The genotype is BB
-The phenotype is brown hair
-The genotype is bb
-The phenotype is blond hair
-The genotype is Bb
-The phenotype is a mixed light brown hair
Therefore:
Both phenotype and genotype are expressions of genetic traits, but the phenotype is the letter form, and the genotype is the physical appearance/description.
