Genetic analysis of haplotypes and variants among living and precontact Native Americans indicates that Native Americans:
A)underwent a huge decline in genetic diversity after Columbus's arrival in the New World.
B)living today appear to be as diverse genetically as their ancient ancestors thousands of years ago.
C)have a genetic structure and haplogroups that are quite recent.
D)living today appear to be more diverse genetically than their ancient ancestors.

Question

Quizplus · Accepted Answer

Studies have shown that the genetic diversity among modern-day Native Americans is similar to that of their ancient ancestors, indicating that there was not a significant decline in genetic diversity after Columbus's arrival. This suggests that Native Americans were able to maintain and preserve their genetic diversity despite the many challenges they faced throughout history. The genetic structure and haplogroups found among Native Americans today are also not recent, but have been present for thousands of years.
