Multifactorial disorder
Multifactorial disorders are
disorders that involve variations in multiple genes joined with environmental
causes. Diseases such as heart disease, type 2 diabetes, and obesity are multifactorial
disorder as they do not have single genetic cause but are caused by a
combination of environmental factors and life style with mutations in multiple
genes.
Ultraviolet light will increase on earth's surface. It will "raise" temperatures and decrease plant populations.
Actually UV rays do not increase temperature, that's wrong.
They cause mutations in several organisms as they modify their DNA. They also cause skin cancer in humans and also cataracts and sunburns.
But they don't increase temperature.
That's carbon dioxide accumulation.
