^*These numbers are not absolute numbers. They are relative to the sapling sampling.

^**Parentage could not be obtained for one admixed sapling in cohort 2, due to a limited number of successfully genotyped SNPs. Total number of admixed trees is 99.

^***Parentage could not be obtained for three saplings in cohort 2, due to a limited number of successfully genotyped SNPs. Total number of saplings is 2487.

Parentage analyses (CERVUS) were conducted with stringent parameter settings, assuming no errors in genotyping (a strict exclusion analysis: 0.0 error rate) and a high confidence level (95%).
