Dr. chan has diagnosed eight-year-old hsu with myopia (nearsightedness). he recommends that hsu spend more time playing outside in the sun. why would dr. chan make this recommendation?

The answer is "Dr. Chan recognizes the strong impact that the environment has on visual genes. "

The expression of genes in a living being can be impacted by the environment, incorporating the outside world in which the living being is found or creates, and in addition the life form's inside world, which incorporates such factors as its hormones and digestion. One noteworthy interior environmental impact that influences quality articulation is sexual orientation, similar to the case with sex-affected and sex-restricted attributes. So also, drugs, synthetic compounds, temperature, and light are among the outer environmental factors that can figure out which qualities are turned on and off, subsequently affecting the manner in which a life form creates and works.
