Kindly help me
I am doing the evolutionary analysis of gene in primates. Initially I estimated ka/ks ratio. Then I applied Tajim's and Fu Li test on human population to check positive selection in human population. My dataset size is 42 and I have out grouped the population with bonobo sequence.
the problem I have faced is that Tajima's d statistics is giving significant results (-2.4) at p value<0.01 but Fu Li result is not statistically significant (-1.6 at 0.1>p value>0.05).
Could I conclude on the basis of single test (Tajima's) that gene is under positive selection in human population.
