Fig. 4: Distribution of SVs between Indigenous communities.
From: The landscape of genomic structural variation in Indigenous Australians
a, PCOA representing the distance between individuals in the cohort based on their SV compositions. The percentage of variance is indicated in parentheses for each principal coordinate axis (PCOA1 and PCOA2). Individuals are coloured according to their group. b, Distribution of NCIG-only variants (Fig. 3) shared among the four NCIG communities. SVs were classified as private (n = 1 individual), community-specific (n > 1 individual in 1 community), widespread (n > 1 individual in more than 1 community) or shared (n > 1 individual in all 4 communities). c, Proportion of private, community-specific, widespread and shared NCIG-only variants among individuals, grouped by community. A total of n = 141 individuals (41 NCIG-P1, 32 NCIG-P2, 9 NCIG-P3, 39 NCIG-P4 and 20 non-NCIG individuals) were examined. The centre line shows the median, box edges delineate the interquartile range (IQR) and whiskers extend to 1.5× IQR from the hinge. d, SV discovery curve in which, starting with a single NCIG individual, the number of new non-redundant SVs is counted as new individuals are iteratively added. SVs shared among all previously added samples are shown as green portions of each bar.
