Atopy is a predisposition toward developing certain allergic hypersensitivity reactions. Atopy may have a hereditary component, although contact with the allergen or irritant must occur before the hypersensitivity reaction can develop.
As of 2012, 63.9 percent of players playing in Major League Baseball are white. There is no way of telling the exact number due to the number of players.
However, the truth is that Latino players make up approximately 25% - 28% of the MLB players. The Dominican Republic has the most players in the MLB with 79 while Venezuela is second with 45 (as of April 2004). Puerto Rico is third with 36. What most people may not know is how many Latino players are Hall of Famers.
