The unique green phenomenon and colour vision.

Abstract

The mode of inheritance of the Unique Green phenomenon is investigated by a new technique. This involves a spectrometer which generates the stimulus in such a manner that the exact position that is neither blue-green nor yellow-green can be compared with neighbouring positions in the spectrum. This technique is used in conjunction with the single field techniques of Waaler to confrim the mode in inheritance he has suggested: that it is an effect carried on the X chromosome. The placing of the Unique Green point in the spectrum is shown to correlate with the mid-matching point in the blue-yellow axis on the Pickford Nicolson Anomaloscope. It is concluded that there may be a highly photolabile visual pigment present, which absorbs maximally at about the yellow region of the spectrum.
