Skin color is determined by the amount/intensity of the sunlight affecting people where they lived over a long period.
Dark skin is best in places where the sun is strong (the tropics) as it prevents the sunlight damaging the skin.
Light skin is best in places where the sun is weak (the temperate regions) because sunlight needs to penetrate the skin to make vitamin "D" and dark skin prevents this penetration when the sun is weak.
Therefore people with dark skin need to make sure that their diet contains extra vitamin D when living in temperate regions and light skinned people need to use sunscreen and cover up on tropical regions so that they do not burn.

Yes, it is possible for twins to have different skin tones if their parents have different genetic backgrounds. This can occur due to genetic variations that result in differences in skin pigmentation.
Yes, two light-skinned individuals can have a baby with brown skin if both parents have genes for darker skin tones that are passed down and expressed in their child. Skin color is determined by a combination of genes from both parents, so a variety of skin tones can result even in families with similar skin colors.
A person's pigment is determined by the amount and type of melanin produced by melanocytes in the skin. Melanin is a pigment that gives skin its color, and variations in melanin production can result in different skin tones. Genetic factors, exposure to sunlight, and certain medical conditions can also affect a person's pigment.
Genetics is a complex interplay of different factors, but a child of a Black father and a White mother could inherit a range of skin tones depending on the specific genetic combinations. The child could be anywhere on the spectrum between the parents' skin tones or may fall in between. Skin color is determined by multiple genes, so it's not possible to predict with certainty what color the baby will be.
Yes, anyone can get a fungal infection regardless of their skin color. Fungal infections are common and can affect people of all races. Proper hygiene and treatment can help manage and prevent these infections.
