Hello, I Am BrotherEye

Genotype is the genetic makeup of an individual eg Bb. Phenotype is the physical appearance eg brown hair.

Explanation:

Your genotype codes for your phenotype — the trait we can actually see. For example, if the blue-eyed parent passed down a blue allele, and the brown-eyed parent passed down a brown allele, the child's genotype will be blue-brown, and his or her phenotype will be brown.
