Over time, humans have steadily increased their movements across the continents of the Earth. Which of the following results has most likely been derived from these movements?

C) increased genetic drift
D) increased gene flow

Question

Quizplus · Accepted Answer

Increased human movement across continents has facilitated the mixing of different populations, leading to increased gene flow. Gene flow is the transfer of genetic variation from one population to another, which can occur when individuals from different populations migrate and reproduce. This movement and subsequent interbreeding among diverse populations reduce genetic differences between populations, enhancing genetic diversity within populations.
