(A) Neighbour-Joining (NJ) tree based on Fst distance, showing genetic relationship for TMPRSS2 gene among the studied population. (B) Matrix showing average paired variation for TMPRSS2 gene, between the population (green) in the upper triangle, within-population (orange) along diagonal, and Nei's distance between populations are shown (blue) in the lower triangle. The obtained value for different variables is directly proportional to the color gradient. (C) The stacked bar-plot represents 47 haplotypes observed in TMPRSS2 Gene among South Asian populations. Frequency and sharing for each haplotype with South Asia and to other geographic regions are indicated with different colored bars.
