Data from all three laboratories (26 separate estimates of phase as a function of genotypes and T) were compiled, 11 for frq⁺ and 15 collectively for frq⁹ and frq¹⁰. Phase was estimated for each individual race tube from cycling during at least 4 days from a total of 51 race tubes for frq⁺ and 75 for frq⁹ and frq¹⁰.
