What is the main blood type of Latin American population? Is it mainly mixed blood?

The ethnic and racial composition of Latin American population is extremely complex. They come from all three basic races of human beings today, namely Mongolian, European and Black Australian. According to textual research, the indigenous Indians in Latin America belong to Mongolian race; Colonists (mainly Spanish and Portuguese) who arrived in Latin America after the American continent was "discovered" and European immigrants (including Italians, French, Germans, Ukrainians and Balkans) who went to America later belonged to the Europa race. From17th century to19th century, blacks were brought in from Africa as slaves. However, at present, there are only a few pure-blood residents who really belong to these three races, and more than half of them are hybrids of the above three races. In addition, there are quite a number of Japanese, Indians, China and other Asian immigrants. Overseas Chinese are mainly concentrated in Brazil, Peru, Mexico, Cuba and Panama. After 1950s, overseas Chinese in Argentina, Venezuela, Chile and Uruguay gradually increased. ?

The population composition of countries in Latin America basically depends on the migration between continents, that is, the source and quantity of immigrants, and also depends on the degree of racial integration. Argentina, Uruguay, Costa Rica and other countries with European immigrants as the main source of population in history, today's residents are mainly white; Among them, whites in Argentina account for 97% of the total population and whites in Uruguay account for 90%; Caribbean island countries such as Haiti, Jamaica, Barbados, Dominica and Saint Lucia, which absorb more slaves, have mainly black residents; In the historical Indian cultural centers, such as Peru and Bolivia, Indians still occupy the majority; Mexico and Central American countries are mainly mixed-race, accounting for 80% ~ 90%.

Mixed-race ... The ethnic composition of Latin American residents is quite complicated. There are not only native Indians, but also later whites and blacks, and there are three kinds of people who intermarry with each other, namely Meso (a hybrid of Indians and European immigrants), Morat (a hybrid of European immigrants and blacks) and Sambo (a hybrid of Indians and blacks). In addition, there are Indians, Japanese, China and Javanese who immigrated from Asia in modern times.
