What percentage range is lactase deficiency reported among African Americans, Native Americans, Asian, and Mediterranean descendants?

Explanation:
Lactase non-persistence, the tendency to lose lactase activity after childhood, is highly prevalent in many non-European-descended populations. Among African Americans, Native Americans, Asians, and many with Mediterranean ancestry, a large majority exhibit lactase deficiency. That’s why the range that best fits this pattern is 70-100%. The other ranges would understate how common deficiency is in these groups, and 100% would be overly absolute.
