Fig 1.
Immigrants, their Quebec-born descendants and related statistics as a function of time.
The number of immigrants and their contributing portion at linear scale (inset shows early history at a magnified scale) (A). The number of all immigrants, Québec-born and their total in logarithmic scale (B). The number of immigrants’ descendants, Nwi, within the 1931–60 population as a function of immigrants’ settlement time (C). Evolution of the survival ratio SR of immigrants and Quebec-born (D). Corresponding plots of the net growth (dci) and net extinction (ai) rates for the immigrants (E) and the Quebec-born (F).
Table 1.
Numbers of immigrants and Québec-born individuals who married in Quebec in five historical periods.
Numbers of distinct and novel (newly introduced, i.e., in addition to those already present and introduced earlier), uniparentally inherited lineages (separately maternal and paternal) are reported as well. Contributing immigrants are those who transmitted their descendant lineages in the 1931–60 population.
Table 2.
Contribution of immigrants from different periods to the 1931–60 Québec, both in the number of their married descendants and in the number of distinct maternal and paternal lineages.
Fig 2.
Effective family size of maternal and paternal lineages at different time points.
Families of immigrants (A), and Quebec-born families (B), showing EFS of contributing, non-contributing descendants and their total (All). Maternal EFS-daughters are shown in dotted lines and paternal EFS-sons in solid lines.
Fig 3.
Correlation between effective family size and survival ratio.
Overlapping plots of total EFSs and EFSd and their survival ratios for the immigrants (A and B) and the Quebec-born lineages (C and D). Their correlation plots are shown in the insets.
Fig 4.
Distribution of marriages and remarriages among marrieds at four time periods.
Different categories of marrieds are specified in the above histograms by their corresponding color codes. The contributing male and female immigrants are in A and B, respectively, whereas all (immigrants and Quebec-born) married men (C) and women (D).
Fig 5.
Comparison of “autosomal” GC of immigrant women and men with GC of their maternal and paternal lines (Nwi) within the 1931–60 population.
The fraction of the immigrant contribution (y-axis) is expressed per year averaged over five years (x-axis).
