@robin1

Ethnic makeup of Cuba: mulattos 51%, whites (primarily of Spanish descent) 37%, blacks 11%, Chinese 1%

Ethnic makeup of Jamaica: black 90.9%, East Indian 1.3%, white 0.2%, Chinese 0.2%, mixed 7.3%, other 0.1%

The Ethnic makeup you posted surely isn’t representative of the population practicing athletics and selected during major events for Cuba.
