<br>
<br>
local structures do not correspond to 'isolation'. They merely indicate that some individuals look genetically different from their neighbours (more so than would be expected at random), which is compatible with what you describe about your populations.
<br>
<br>
Cheers<br>

<div dir="ltr">Dear all,<br>
I have a question that<span class="b1"> </span><span class="b2">conc</span><span class="b3">erns</span><span class="b4"> me
</span><span class="b3">a li</span><span class="b2">ttle</span><span class="b1"> b</span>it. I realised a sPCA considering 20 breeds. The Spca showed a global spatial structure (genetic cline) and 3 breeds appeared "particular" (local structure). These 3 breeds
are characterized by the lowest Allelic richness, and one of them showed the greatest inbreeding coefficient. So I am very embarrassed.... is this a spurious clustering (as Spca would be skewed by the poorest genetic diversity of these breeds....), or can
I really conclude that these breeds are isolated and so genetically original (as a result genetic diversity is lower for these breeds).
<span class="b4">which</span><span class="b3"> ca</span><span class="b2">me firs</span><span class="b3">t th</span><span class="b4">e
