Question

As the human population spread out of Africa into new regions, genetic diversity Group of answer choices went up as an adaptation to new environments. went down because each expansion had a chance of leaving behind one or more genetic variants. maintained an equilibrium because population density stayed the same while territory expanded. varies randomly, do some populations has greatly increased variation while some had greatly decreased variation.

Answer 1

Genetic diversity decreased as the human population migrated from Africa to other continents because each migration had a chance to obliterate one or more genetic variants.

What is genetic diversity?

The term "genetic diversity" refers to the entire gene pool that a population or species possesses in a specific habitat.

During migration, genetic diversity is essential for adjusting to new environmental situations.

The genetic diversity decreased when the human population migrated from Africa to other continents since each migration had a chance of bringing with it one or more genetic variants.

Answer 2

As the human population spread out of Africa into new regions, genetic diversity went down due each expansion had a chance of leaving behind one or more genetic variants.

What is genetic diversity?

Genetic diversity makes reference to all gene pool that a population  and/or species exhibit in a given environment.

Genetic diversity is fundamental to adapt new environmental conditions during migration.

In conclusion, as the human population spread out of Africa into new regions, genetic diversity went down because each expansion had a chance of leaving behind one or more genetic variants.
