- Tickets are issued as a series containing 360 different tickets.
- On average, the estimated probability of expressing an opsin on this ticket is 1 in 1.57.
- Chances of expressing an opsin and the number of tickets in each series expressing an opsin are established before distribution of tickets begins, and will change as opsins are expressed. Tickets may remain even after all red, green, and blue opsins have been expressed.
- The chances of expressing an opsin on this ticket are based upon data derived from research into “Stochastic Human Opsin Choice” by Kiara Eldred at Johnston and Hattar Labs, Johns Hopkins University (Robert J. Johnston Jr., P.I.).
- Cone opsin first begins to be expressed between 129 and 150 days.
- Cone cells continue to be added to the retina’s mosaic until day 360.
- At 360 days, cones are distributed as 25% blue, 75% red / green.
- In an adult retina, cones are estimated at ~10% blue, ~30-60% red, ~30-60% green.
- Electron Micrographs of human cone cells are sourced from: Curcio, Christine A., Kimberly A. Allen, Kenneth R. Sloan, Connie L. Lerea, James B. Hurley, Ingrid B. Klock, and Ann H. Milam. “Distribution and Morphology of Human Cone Photoreceptors Stained with Anti-blue Opsin.” The Journal of Comparative Neurology J. Comp. Neurol. 312.4 (1991): 610-24.
