One significant environmental factor that affects skin color in humans is ultraviolet (UV) radiation from sunlight. Increased exposure to UV radiation stimulates the production of melanin, the pigment responsible for skin color, leading to darker skin tones as a protective adaptation against skin damage and skin cancer. Conversely, populations in regions with less sunlight typically have lighter skin, which allows for better synthesis of vitamin D in low UV conditions. This adaptation highlights the interplay between environment and human Biology in determining skin color.

Which is an environmental factors that affects skin color in humans?
Sunlight (sun's UV radiation) is the major environmental factor that affects skin color in humans. Skin pigmentation (melanin) is responsible for skin color and it evolves primarily to regulate the amount of ultraviolet radiation penetrating the skin.
Which is an enviromental factor that affects skin color in humans?
amount of sunlight absorbed :)
What factor effects the intensity of light the color of light and the type of electromagnetic radiation that is given off by the electron?
Photoelectric effect
How can an environment factor can influence a trait?
Complex traits are those that are influenced by more than one factor. The factors can be genetic or environmental.
Can humans see the color yellow?
Yes, humans can see the color yellow.
Can color be a definitive factor in determining a mineral?
can color be a denitive factor in determinig a mineral
Which example illustrates the modification of a phenotype by an environmental factor?
An example of the modification of a phenotype by an environmental factor is the coloration of the Arctic hare. During summer, the hare has a brown coat to blend in with the environment, while in winter, it changes to white to camouflage against the snow. This change in fur color is not due to genetic alteration but is a phenotypic response to seasonal environmental conditions. Thus, the hare's phenotype is directly influenced by its surroundings.
Which is not a factor that effects the rate of weathering in rocks?
The color of the rock is not a factor that directly affects the rate of weathering. Factors such as temperature, moisture, chemicals, and the composition of the rock itself play a more significant role in determining the rate of weathering.
What are the effects of color blindness?
You can not see color.
What is body color?
Body color refers to the overall hue or pigmentation of an organism's skin, fur, feathers, or scales, which can vary widely among species. It often serves various functions, such as camouflage, mating displays, or signaling health. In humans, body color is influenced by genetic factors, melanin levels, and environmental factors. Additionally, body color can play a role in social interactions and perceptions in both animals and humans.
What color do humans react to the fastest?
The color red is known to evoke the fastest reaction in humans.
Is there only one gene that affects hair color in humans?
No, hair color in humans is influenced by multiple genes, not just one. Variants in genes such as MC1R, ASIP, and others contribute to the wide range of hair colors observed. These genes interact in complex ways, leading to the diverse phenotypes seen in the population. Additionally, environmental factors and aging can also affect hair color.
