Figure 1. Drosophila prepared for pseudopupil
White eyed Drosophila fixed to a microscope slide. This photograph was made with the help of Mr. H. Leertouwer in 1978 when WSS was on a research fellowship at Rijksuniversiteit Groningen, the Netherlands. The fly on the left was reared on the vitamin A replete diet, while the one on the right was vitamin A deprived. Note a slight off white coloring of the eye of the vitamin A replete fly, presumably due to visual pigments and possibly related with the pink seen in Figure 9. Flies need not be fixed to a slide; this is covered in the "Rhodopsin-metarhodopsin conversions" of the Discussion.
