Mexico has produced the most world champions ever than any other country. They're the number one boxing country in the world with current still number 1 with about 10 world champs not counting Mexican Americans because they count for America. Then America comes in #2 because of the African Americans. They've produced so many legends and have dominated the sport as well. Then 3 is Puerto Rico. But I say Puerto Rico only has one fighter left who's worth mentioning and it's Danny Garcia. And I say they're on their way down to being number 4 in Countries. But the reason I say Mexicans dominate is because of the Aztec warrior blood in their veins and they have rough lives coming from poverty and discrimination makes em tough mentally and physically. Same for Afro Americans. Come from poverty discrimination making em tough the same way. Puerto Ricans I'm not sure. They've only had 69 world champs and currently still 3 compared to Mexicans with over 200 champs counting mexican Americans. So idk why. And then again Mexicans have also contributed to Americans domination in the sport( Mexican American champs such as Oscar de la Hoya ). But UFC yes it should be considered under Mexican American dominance because of The baddest man in the world Cain Velasquez. No champ under heavyweight will beat him nor any heavyweight. So yes UFC is in Mexican hands as well. But 2nd in UFC should be brazilians then Afro Americans. But regarding Boxing the sport is dominated by Mexicans/Mexican Americans, Black Americans, then Ricans. But mainly Mexicans and African Americans.

Well depends on what you mean by dominated by whites. Because the very first UFC championship was won by a Brazilian. In fact 3 out of the 4 first UFC tournaments were won by a Brazilian. There were alot of standout American's. The UFC Heavyweight champion was won by an american, who was, 2 events later, beat out by an African American. If you are looking at Current Day UFC champions, Out of the 9 current chamipons and interim champions, which would make it 10, There is 3 Brazilians, 2 African Americans, 2 Mexican Americans, 1 Canadian, 1 White American, and 1 South Korean. About 1 year ago, there was about 5 Brazilians Champions, Holding the HW, LHW, MW, FW, and BW Champions. When it comes to MMA/UFC Brazilians hold the top of the rankings.

African Americana's not Africans , not Mexicans Africans americans are the best fighters in the world Mexicans are second. I am not saying this to be disrespectful to any other race it is just a fact. There are many theory's why this small group of black men rule the sporting world. There are many more blacks in other parts of the world but only the American black dominate. Some think it is because of slavery I to feel that this has a lot to do with it but I also think that this group of black people just want it more than any other group.Canelo lost that fight to Austin Trout but they gave it to Canelo. Black people have always known that they had to be twice as good as whites just to get a job or play sports this also has a lot to do with it.

I'd say one factor is that they are so motivated. African Americans and Mexicans have great motivation for anything they do. it's a great trait!

UFC used to be dominted by whites, now it's dominated by African-American's but mainly Mexcians with Cain Velasquez being the top dog. Boxing has always been domiated by African-American's and Mexicans but mainly Mexicans, Mexico has the most championships in boxing and the most legendary fighters to have ever ever come out than any other country. Pacquiao's downfall came by the hands of a Mexican, and many speculate Saul Canelo Alvarez will be Mayweathers downfall and by the way he fights it looks like that may be the case. My question is why? why don't any other countries produce fighting champions? it seems like when one Mexican fighter falls either he comes back stronger or more come out nowhere and rise to the top. Why? I'd like to see Boxing be more diverse and have different fighters -.-
