One theory is that individuals of a species could look different today if they were exposed to different environmental conditions. What is culture and how does culture differ between human and nonhuman primates? The genotype that an individual possesses for a trait, in turn, determines the phenotype the observable characteristicssuch as whether that individual actually ends up with straight, wavy, or curly hair.
