Answer:
Although people living in low latitudes have high levels of eumelanin, this pigment can be found in people around the world (because it is predominant in people with brunette hair)
Explanation:
In animals and humans, melanin pigments play key roles in eye, hair, and skin coloration. Basically, there are three main types of melanin pigments: eumelanin (brown-black and insoluble), pheomelanin (yellow-red and soluble in alkali solution) and neuromelanin (found in some parts of the brain). Eumelanin is predominant in black people and brunette hair people, this being consequently found around the world. There are two distinct classes of eumelanin: black eumelanin and brown eumelanin, which differ in their patterns of polymeric bonds, and they have an incidence on the type of coloration (e.g., black eumelanin is found in people with grey hair).
A sex-linked trait is a trait that is carried by the X chromosomes in females but it is not expressed(the phenotype). Females are only carriers because they have two copies of the X chromosome [one of them carries the trait and the other does not]. Males who inherit one copy of the X chromosome often get the trait (because the trait is in either one copy or the other of the X chromosome) and express it while their Y chromosome would became recessive. Thus, only males express sex-linked traits such as hemophilia or color blindness

The ozone layer is a stratospheric region composed of Ozone (Triatomic Oxygen)
CFC´s (Chlorofluorcarbons) are broken down by ultraviolet radioation to release chloride ions wich react with ozone breaking it down into oxygen.
One chlorine atom can destroy 100.000 ozone molecules - smallamounts of CFC can break down large amounts of ozone.
The thinning of the ozone layer by CFCs reduces the absorption of UV light in the stratosphere
