The yellow mutation in the frog Rana rugosa: pigment organelle deformities in the three types of chromatophore.
Crossing experiments revealed that a single recessive gene mutation (yellow) gives rise to the yellow phenotype of Rana rugosa in Japan. Ultrastructural observation of dermal chromatophores showed that the pigment organelles; melanosomes, pterinosomes, and reflecting platelets, all had structural deformities. This suggests that the yellow gene acts at the level of a primordial pigment organelle common to the three types of chromatophore.
