I want to know the answer to the following question:
What mutation did Takahashi discover in 1994?
All the background I'm provided with is that "Ron Konopka and Seymour Benzer isolated the first clock mutant in Drosophila in the early 1970s and mapped the "period" gene, the first discovered genetic determinant of behavioral rhythmicity.". Is that enough to answer the question?
Answer: no
