Parentage assignment among breeding adult Bolson tortoises (Gopherus flavomarginatus) for yearly cohorts of hatchlings.

Best match data (A) utilize stringency criterion with 3 independent analyses among parent pairs. All data (B) shows most likely assignments for all individuals tested (hatchlings, n = 241; potential parents, n = 30). Parenthetical values indicate discrepancies calculated for years 2010–2012 between number of offspring assigned via genetic analysis and the known number of offspring. Positive values indicate number missed by genetic assignment (underestimate) and negative numbers indicate increased number of offspring incorrectly assigned to a female (overestimate).
