What's the similarities between phenotype and genotype? Pleas help meee

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.

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
