Why are black or pseudomelanistic tigers only found in Similipal tiger reserve, India? What is causing the reappearance of long-lost rare colouration phenotypes like golden and white in wild tiger populations? I am interested in colouration phenotypes in tigers, their genetic and evolutionary drivers, and their implications for individual and population health. My research involves identifying the genetic mutation associated with disruption-of-stripes or pseudomelanistic phenotype, investigating the evolutionary drivers of white, golden and pseudomelanistic phenotypes in wild tiger populations, and understanding the potential loss of function mutations contributing to inbreeding depression often associated with captive populations of rare coloured tigers.
