Height is the trait that is regulated by genetic and environmental factors. The type of the gene present in the genome of the organism and environmental factors such as nutrition, physical activity, surroundings etc. regulate the height of the organisms. If environmental factors are kept constant, the height would be regulated by genetic factors only.
