Abstract
A total of 2000 unrelated school children were screened for colorblindness in Visachapatnam, India. Whether the protan and deutan defects are the result of mutations at one locus or at two loci has not been completely resolved, alhough the evidence favors two discrete loci. The investigation was extended to the families of the 10 color vision anomalous children to study the tescendance patterns of these two loci. The importance of these observations are discussed.
