Sickle-cell anemia would be a pretty obvious example.

The only obvious thing here is your racism, my friend. Own it!!!

Propensity for sickle-cell anemia is related to the spread of malaria in the past, not to color of ones skin. Brown people HAPPEN to live in areas where malaria was and is widespread.

Correct. 

Just out of curosity, do they still make yall do Punnett squares in school? It's a really good way to demonstrate how these traits are passed down through populations, though certainly just a crash course understanding of the science. 

Now that we have clearly established your racism,

Define racism.

Let's dig a bit deeper into your scientifically uninformed  racism: How do we determine the tone of ones skin in DNA tests?

Melanin production can be measured through an identified 169 functionally diverse genes; some of the most recently discovered being KLF6 and COMMD3 after a multi-year study by Dr. Vivek Bajpai of Oklahoma University and assisted by Stanford Uni. - KLF6 confirming melanin production in various other animals and COMMD3 having the power to regulate the acidity of melanin.

This is incredibly useful for researchers and doctors; understanding the processes of melanin can directly help us treat various skin diseases and cancers; skin cancer and breast cancer  (COMMD3) breakthroughs being two of the most obvious, as well as treatment for non-severe conditions such as vitiligo. 

KLF6's confirmation in other species - as well as other recently identified markers of melanin production - is also showing potential in reducing the damage that is caused by melanin-infected fungi and bacteria; higher rates of melanin in these corelate with increased rates of pathogenic contamination within crop yields and in humans by giving us the potential to identify these genes and limit their production with these microbes.
