Hello I am approaching with genetic analysis and FStat and I have a lot of doubts. If I have a sample composed by a single population (so i don'thave a subdivision in subpopulations) why cannot I calculate deviation from Hardy-Weinberg equilibrium with FStat? And when I have more than one population which parameters should I choose from the FStat window? And how could I read the output file? I am really confused and I appreciate any suggestion! Thanks
