Ν: number of analysed individuals, Ar: mean allelic richness, FIS: inbreeding coefficient, He: expected heterozygosity, Ho: observed heterozygosity, PHW: p-value of Hardy-Weinberg.
Figure 1. Sampling locations of wild birds in the UK, Greece and North Macedonia.
Figure 2. Haplotype network of the Cyt-B sequences including three Perdix perdix Genbank sequences. Each circle represents a distinct haplotype or maternal lineage and the markers on the lines between them represent the number of base-pair differences between each lineage.
Figure 3. Haplotype network of the CR sequences including the Eastern (E) and Western (W) haplotypes of Liukkonen et al., 2002. Each circle represents a distinct haplotype or maternal lineage and the markers on the lines between them represent the number of base pairs between each lineage. The new haplotypes identified in this study are numbered in red.
Figure 4. A genetic Structure plot of the global microsatellite database, consisting of 8 microsatellites. Each bar represents an individual bird and the proportion of green colour represents the proportion of “western” genetic ancestry, and the proportion of red represents the proportion of “eastern” genetic ancestry.
Figure 5 : Principal Component Analysis (PCA) of the 81 individuals based on 2300 SNPs.
Figure 6. Genetic Structure plot of the wild-caught Greek and North Macedonia birds based on 2300 SNPs. Each bar represents an individual bird and the proportion of each colour represents the proportion of each of five genetic ancestries. The locations refer to those shown in Figure 1.
Figure 7. A genetic structure plot focusing on the levels of hybridisation in the sampled Grey partridges using 2300 SNPs. Each bar represents an individual bird and the proportion of orange colour represents the proportion of “western” genetic ancestry, and the proportion of blue represents the proportion of “eastern” genetic ancestry.
