What is less genetic diversity?

Species with a higher diversity have a lower tendency to become extinct. The greater the genetic diversity within a species, the greater is the chance of that species to survive. Conversely, the lower the genetic diversity within a species, the lower is the chance of survival.

Which country has highest genetic diversity?

In the most comprehensive study of African genetic diversity to date, a team of international scientists, led by Dr Sarah Tishkoff from the University of Pennsylvania in Philadelphia, US, has revealed Africa to be the most genetically diverse continent on Earth.

What country has the smallest gene pool?

Vatican City
Vatican City is the country with the smallest gene pool in the world.

What leads to the least amount of genetic diversity?

Inbreeding, genetic drift, restricted gene flow, and small population size all contribute to a reduction in genetic diversity. Fragmented and threatened populations are typically exposed to these conditions, which is likely to increase their risk of extinction (Saccheri et al.

Is high or low genetic diversity better?

Large populations are more likely to maintain genetic material and thus generally have higher genetic diversity. Small populations are more likely to experience the loss of diversity over time by random chance, which is called genetic drift.

Who are the most genetically diverse people on Earth?

Pygmies and the bushmen of Africa are the most genetically diverse people on Earth. For some genetic traits they have as many as 17 variations, where the rest of the peoples of Earth have only two or three.

What is the most genetically diverse species?

The split gill mushroom (Schizophyllum commune) has a nucleotide diversity of up to 20\%, according to a 2015 study published in the journal Molecular Biology and Evolution. According to the study, that’s the greatest genetic diversity reported for any eukaryote, or organism whose cells have a nucleus.
