Why human skin coloration is not sufficiently explained by polygenic inheritance? it is because of the other aspect that affects the skin, for example sun exposure which is the effect of environment not by genes. If a person is exposed in the sun, her skin gets darker compare to what it used to be.
Well I think I might know this since I was born and grew up in WI, but don't be 100% dependent with my answer because I'm only in 7th grade and I am doing high school stuff. Well my guess is the proportion of the genes is 1/2 because when a offspring is produced the genes are split from each parent rather its a human baby, a mammal, a fish, a reptile, a insect, or a plant. Although, I don't know what f1 means except for it being a control on the computer lol. But like I said I'm only in 7th grade so I don't know everything but I'm smarter than a average 7th grader.
Hope this helps! (it probably wont though)

<h3>Further explanation
</h3>
Humans impact the environment in so many ways such as overpopulation, overfishing, pollution, and deforestation. This condition leads to many other problems: poor air and water quality, climate change, and soil erosion. Increasing population means increasing demand for consumption that may destroy the natural resources and environment.
The government or an organization creates environmental policies to regulate environmental issues and to reduce human impact on the environment. According to McCormick environmental policy is “any action deliberately taken to manage human activities to prevent, reduce, or mitigate harmful effects on nature and natural resources, and ensuring that man-made changes to the environment do not have harmful effects on humans or the environment.”
The policy regulates the use of resources and to reduce pollution to promote human welfare and protect natural resources. Some example of environmental policy, governments forbade the use of hazardous substances in agriculture or apply maximum emission levels for the industry to ensure minimum environmental quality.
