Which best describes the factors that affect a phenotype?
O
A. The genotype and the environment both affect phenotype.
B. The phenotype is determined only by the environment.
O
c. Phenotype is only controlled by the genotype.
D. Nutrition is the only thing that determines the phenotype.

The answer is A. The genotype is the genetic makeup of the organism, it affects traits. The phenotype displays those traits, maybe not all of them, due to dominant and recessive genes. The environment also influences the genotype and phenotype by evolution and adaptations. It alters the genotype, which affects what the organism will display (phenotype).
