I want to know the answer to the following question:
The 75% rule states how much of a population must lie outside the range of other populations for a defining set of characters?
All the background I'm provided with is that "Dean Amadon proposed in 1949 that subspecies would be defined according to the seventy-five percent rule which means that 75% of a population must lie outside 99% of the range of other populations for a given defining morphological character or a set of characters.". Is that enough to answer the question?
Answer: yes
