The DNA you inherit changes your traits which we call your phenotype. Which statement best describes a polygenic trait1 point -A polygenic trait is only controlled by one environmental factor. Temperature humidity other factors may affect cannabis phenotypes.

5Most individuals will be of average height. Exposure to UV radiation will correct genetic mutations in humans. Multiple genes and environmental factors.

4Mendelian traits cannot be shown on a bell curve. Some traits are largely determined by the genotype while other traits are largely determined by environmental factors. Thus the phenotype is affected by environment not genotype.
