The item which gives skin color genetically is called blood thinner? True of false?

False

Explanation:

Melanin is the substance that gives skin, hair, and eyes their color. Melanin is also found in the light-sensitive tissue at the back of the eye (the retina), where it plays a role in normal vision. Melanocytes make two forms of melanin, eumelanin and pheomelanin.

I believe it is false.

Explanation:

Since we are talking about genetically, it would be melanin that gives skin its color. Blood thinner prevents blood clots, though they dont usually affect skin color and aren't genetic.
