Why does Africa have such a diverse population?
The researchers found that many Africans have some Eurasian DNA within their genetic ancestry, which suggests that Eurasians migrated back into Africa many thousands of years after they first left. And several of the populations were descended from the Bantu, a group that spread across Africa about 5,000 years ago.
Is there more genetic diversity in Africa?
Africans are more diverse genetically than the inhabitants of the rest of the world combined, according to a sweeping study that carried researchers into remote valleys and mountaintops to sample the bloodlines of more than 100 distinct populations.
Are Europeans and Africans genetically different?
The average nucleotide diversity (pi) for the 50 segments is only 0.061% +/- 0.010% among Asians and 0.064% +/- 0.011% among Europeans but almost twice as high (0.115% +/- 0.016%) among Africans. The African diversity estimate is even higher than that between Africans and Eurasians (0.096% +/- 0.012%).
Is black dominant or recessive?
Moreover, brown body color is the dominant phenotype, and black body color is the recessive phenotype. Figure 3: Different genotypes can produce the same phenotype. Researchers rely on a type of shorthand to represent the different alleles of a gene.

What does diversity mean in Africa?
The diversity in Africa, especially sub-Sahara, is normally centered around culture, ethnicity, gender, religion, etc. … Notable among these elements of diversity is ethnicity, which sometimes bring predicament to the continent in the form of ethnic conflicts among others.
Why does Africa have the greatest genetic diversity?
Africa is an important region to study human genetic diversity because of its complex population history and the dramatic variation in climate, diet, and exposure to infectious disease, which result in high levels of genetic and phenotypic variation in African populations.
What is genetics diversity?
Genetic Diversity refers to the range of different inherited traits within a species. In a species with high genetic diversity, there would be many individuals with a wide variety of different traits. Genetic diversity is critical for a population to adapt to changing environments.
