    Author: Tandon VK, Pandey N, Shukla BR.
    Journal: Anthropol Anz; 1979 Jan; 37(1):42-9. PubMed ID: 312621.
    Abstract:
    On n = 320 nonrelated Kureel Chamars (160 males, 160 females) from Lucknow and neighbouring villages and n = 314 nonrelated Jaiswar Chamars (160 males, 154 females) from Jaunpur the frequency of colourvision deficiency was examined. In the Kureel Chamars the frequency of deuteranopia comes to a total of 1.25% (males: 25%, females: 0.0%), in the Jaiswar Chamars to a total of 1.91% (males: 3.13%, females: 0.65%). Protanopes were only found in the Kureel Chamars (0.63%; males: 1.25%, females: 0.0%). These observations are discussed and compared with those obtained on other Indian populations.
