Common Pitfalls When Studying Adaptive Genetic Variation The use of large SNP datasets may provide insightful information about the genetic composition of populations; however, by the very nature of being a large dataset (e.g., millions of variant sites), many statistical analyses may be significant (e.g., p < 0.001) but not necessarily biologically relevant (Sham and Purcell 2014 ; Kaler and Purcell 2019 ).
