Answer:
Genotype codes for phenotype.
Step-by-step explanation:
Your genotype is your genetics.
Your phenotype is your appearance, for example, brown or blue eyes.
Say you have blue eyes, and it's a recessive trait, represented by b. Brown is a dominant trait, so it would be represented by B. Your genotype would be bb, because you wouldn't possess the dominant brown-eye gene. For further example:
BB = Brown
Bb = Brown
bb = Blue
