At the end, we can say that Heredity and environment both are significant factors in the development of personality. If heredity is the base, environment is the structure. If heredity is the seed, environment is the soil. If heredity is the soul, environment is the body. As we cannot separate the soul from the body in a living human being, so we cannot separate the heredity from environment.
Thus heredity and environment are complementary.
