Scatter plot of Principal Coordinates Analysis (PCoA) based on individual pairwise genetic distances for the studied broodstocks of the European huchen

Unrooted neighbor-joining tree of individuals based on allele sharing distances (DAS). The arrow indicates one individual that was included in a cluster not matching its origin.
Figure 3
Plot of the rate of change in the log probability of data between successive K values (ΔK). The most likely number of genetic clusters was determined for the studied European huchen broodstocks based on the ΔK method.

Structure plot of individuals sorted by admixture coefficients (q) for putative K = 2. Each vertical bar denotes one individual.
Table 1
Results of assignment tests for four examined European huchen broodstocks
| Broodstock | Leave one method | Individual assignment | ||
|---|---|---|---|---|
| N | % correct | LM | AVG | |
| Poland | 30 | 73.3 | 31.0 | 0.8255 |
| Germany | 32 | 100.0 | 0.0 | 0.9998 |
| Slovakia | 44 | 100.0 | 0.0 | 0.9999 |
| Ukraine | 29 | 69.0 | 26.7 | 0.9242 |
[i] N – number of individuals, % correct – ratio of correct assignments to baseline broodstocks in the leave-one-out test, LM – largest misidentification in each broodstock, AVG – average probabilities for all specimens in the mixture set belonging to each predefined broodstock.
