Which statement accurately describes the relation between genotype and phenotype in this material?

Explanation:
Genotype provides the genetic blueprint that determines which proteins and regulatory systems are built, and those gene products drive the traits you observe as phenotype. In other words, the information inside the genes sets what can be expressed, so the genotype largely shapes the phenotype. The environment can influence how strongly or when those genes are expressed, but it doesn’t change the underlying genetic code. Chromosome number isn’t the direct determinant of a trait, and environmental factors don’t rewrite the genotype.
