I analysed my samples for isolation-by-distance using a mantel test in Adegenet package. I am not sure if the histogram below shows that my samples has a clear isolation by distance pattern.
Below is the summary of result from the adegenet.
Summary of results
Monte-Carlo test
Call: mantel.randtest(m1 = Dgen, m2 = Dgeo)
Observation: 0.1486482
Based on 999 replicates
Simulated p-value: 0.009
Alternative hypothesis: greater
Std.Obs: 3.3053629175
Expectation: 0.0009153189

Also, for the second plot I am not really sure if it is a normal result and I am a bit confused how to interpret it. I hope anyone can help me interpret these plots.
Thank you so much.
