Final answer:
There is much greater variation within each of the traditional so-called races than between them.
Step-by-step explanation:
The statement True, there is much greater variation within each of the traditional so-called races than between them, is correct.
Scientifically speaking, there is more genetic variation within racial categories than between them. Geneticists have demonstrated that humans share more genetic similarities with individuals from other races than with individuals from the same race. This means that race is not a reliable predictor of genetic variation or ancestry.
For example, if we compare individuals within the same racial category, such as individuals of African descent or individuals of European descent, we will find more genetic diversity within these groups compared to the genetic differences between these groups.
